Do You Speak Chicken? Flock Social Behavior and How Chickens Communicate

By Leigh - 

OK - so I'm not exactly the Rosetta Stone of the chicken world, but I think most people who keep poultry in a natural setting soon see for themselves that chickens communicate with each other. While much of their language is nonverbal, chickens do use a wide variety of vocalizations also.

So, what do chickens talk about?

The Flock:
We've all heard and witnessed flock pecking order. Every flock develops their own hierarchy within days of being put together in a coop, run or free range environment. This hierarchy also changes as new birds are added or removed from the flock. 


Flock status is developed through both verbal and nonverbal communications. Birds working to establish themselves as being of a higher rank than another bird will growl, screech, peck and jump at other birds. This behavior will continue until one bird relents and submits to the other bird by running away. This can often be seen at roosting time when older birds refuse to allow younger or birds of lower status on the same roost. (For this reason, multiple roosts are helpful in larger flocks.)

Chickens do develop lasting relationships with each other. It is very common to have various sets of BFFs within the flock. In fact, if something bad happens to one of the partners in this kind of friendship relationship, the other bird will often behave in an 'off' manner for some time following it's friend's disappearance. The remaining bird may search the yard daily or refuse to leave the spot it last saw its friend. Interestingly in cases where one friend has been isolated due to an injury and then reintroduced to the flock, the bird's friendship partner will usually instantly recognize it and the bond will resume right away.

Cockerels and roosters will spar with each other to decide who will be the dominant rooster in the flock. In most cases no blood is drawn and the argument will end when one rooster runs away. Many roosters can happily coexist in a free ranged flock provided there is a rooster to hen ratio of at least 3 hens to every 1 rooster. (More hens per roo is better.)



A flock's pecking order becomes very obvious at feeding time. The top hens will eat first, chasing off the lower-ranked and younger birds. Only when the top hens have eaten their fill will the lower-ranked birds be allowed to eat. Usually roosters will eat last, but it is not uncommon for a head rooster to eat before younger cockerels are allowed to dine.

If any of the flock witness a potential danger, they may take up a group cacophony danger call. I can only guess that this particular call is meant to frighten off predators. It is very similar to the Egg Song (more on the egg song later) and starts with a loud, frightened "buk-buk-buk-buk BAGAWK!" The end part of the call goes up not only in volume but in tone. A story - last winter my family went to visit a farm with Silkies that were kept in a barn. One of us sneezed and we were instantly almost deafened by this warning call as it was taken up by perhaps 200 Silkies all at once! If I were a domestic cat or small dog, I might think twice about getting any closer.

Of course there are times that blood will be drawn by hens or roosters alike. The roosters of some breeds are more aggressive than others and these birds may continue a fight after another rooster has backed down. Research your breeds and observe the interactions between roosters regularly to make sure you don't have problems like this in your yard.


It's also not uncommon to hear of someone who has a hen that is being picked on by flock mates to the point of being bald and bloody. While it is normal to have some pecking and disagreements among flock members, it is rare to see this kind of abuse within a free ranged flock. Free ranged birds can stay away from a nemesis throughout the day. Picking and bullying is most often seen in flocks that are kept in a coop or run for most or all of the day. It can be a sign of boredom, not enough meat protein in the diet or over-crowding. Feeding plenty of meat protein each week and placing stumps, toys and a variety of perches in the run can help, but in the most severe cases either the main abuser or the main victim should be removed from the flock. If the problems continue, it is time to assess the amount of coop and run space your birds have. Check out our article on space requirements here:  


Rooster to Hen Communications:

(A rooster calls his flock over to a treat.)

If you have both hens and roosters, chances are you have witnessed your rooster vocally calling his hens over to share a special treat he has found. When a rooster locates a particularly juicy bug or super yummy plant, he will make an excited, low clucking sound that the hens recognize as a signal to come over and look. This behavior has two purposes. First, the rooster helps to insure his hens are getting proper nutrition. Second, once the rooster gains the trust of his hens, it becomes easier for him to mount and breed them.


The mating communication is primarily nonverbal. The rooster will drop a wing and spread it out to signal he wants to mate. He will do a rather funny looking shuffle-dance with his feet as he displays his roosterish plumage. Generally the hen will squat at this time, but if she does not want to accept his amorous advances, she may screech or cluck loudly and run away. The sound an unwilling hen makes is often recognizable to the human ear as being distressed or angry.

How Do Chickens "Do It?" Chicken Sex Explained

Roosters are very serious about their job of keeping their flock safe. While hens and chicks roam the yard searching for treats, a rooster will keep his eyes open for danger throughout the day. If he spots anything that looks dangerous, he will make a loud, low growling or screeching sound to warn the rest of the flock. At his sound, the rest of the flock will freeze and look for the source of the danger and then run for cover. Ironically, flock members quickly learn to ignore the warnings of certain young cockerels that alarm over everything from a lizard to a falling leaf. Yes - the hens know which roosters to listen to and which to ignore just by the sound of their voice.


Lastly, roosters will quietly "talk" to their flock at roosting time. If you are quiet, you can hear the vocal exchange going on in the coop at dusk as the chickens are getting settled for the night. The rooster will make low, gentle clucking sounds as will many of the hens.


Hen to Chick Communication:


There are few things more enjoyable to watch than a hen with her brood of chicks! 

Like roosters, hens have a variety of calls to guide their chicks. For chickens it seems that language starts even before hatch. Once a chick internally pips (breaks through the internal membrane of the egg and begins breathing air) it can be heard peeping inside the shell. The mother bird hears this and will coo and cluck to her babies as they hatch. Prior to hearing this peeping, the broody hen is generally completely quiet. The only exception to the quiet broody rule is that many hens will growl rather ferociously if their nest is approached.


(Get the %&$# away from my eggs!)

Most of my own hens will start free ranging with their chicks by the second day post-hatch. She will cluck almost continuously as they explore, and the chicks will peep back the entire time. By doing this, they all keep track of each other.

When mom finds something edible, she will cluck excitedly as she picks up and drops the object over and over again until one of the chicks gathers the courage to try it. Within a few days, the chicks have learned to trust their mother's judgement and will quickly gobble up anything she offers. 


Hens alert their chicks to possible danger with a low growling sound. When the chicks hear this, they instinctively know to take cover under mom. If the mother determines there is an actual danger, she also uses body language to warn off a predator... or even just other chickens. For the first few weeks, she will do what she can to keep her flock mates far away from her babies!


(A broody hen will take on the 'Turkey' stance to make herself look larger and more threatening.)
(Below - the same hen... in a more relaxed stance.)

Chicks learn by watching their mother or other chicks. If you have chicks in a brooder, you can teach them to try new foods or use a different waterer by clucking like a mother hen with a quick "buk, buk, buk, buk..." and tapping the new treat or object with one finger. Day-old chicks will race right over to see what you are showing them. If one learns to eat something new or drink from a different kind of waterer, it will only be a matter of hours before the rest of the chicks pick up the behavior from the first one. (Cool, huh?) 

The Egg Song:
The egg song is very similar to the flock warning call: "buk-buk-buk-buk BAGAWK!" The subtle difference is the tone that is used. It can be very hard to tell the two apart, but once a person has become very familiar with their flock, they might be able to liken the warning call to a frightened crowd of people and the egg song to a joyous celebration. Hens seem to want everyone to know of their success in creating the most wonderful egg of all time (every day) and others will often take up the celebratory cry also.

In my own flock I have a few that have very average egg songs, one who clearly has the spirit of an opera singer trapped within her, and one who sounds a tad like Bruce Springsteen. Yes - they are all quite individual in their calls.

Battery Hens & Meat Birds in Industrial Settings

Studies of hens or meat birds that have been brought out of an industrial-type setting have proven quite fascinating! It is common practice for battery hens to be debeaked (the tip of the beak is literally removed) because in these crowded conditions it is common for the birds to pick on or even cannibalize one another. Social interactions of these birds are limited to the 2-3 other birds stuffed into the same small cage. There is rarely natural sunlight in these settings, no dust for bathing, no grass in which to hunt bugs in... only the wire of a cage floor.


Even in so-called "free range" settings, the industry does not provide a good environment for relationships to develop between chickens. I mean, seriously - if you were in a warehouse packed wall-to-wall with other people, you might make a friend, but it would be difficult to find them ever again in the throng.

The noise in these settings is almost deafening so it would be nearly impossible for the chickens to communicate well with each other. They don't have a choice as to who they spend their time with or what they spend their time doing.


As a result of these conditions, it has been observed that the chickens seem to lack personality. Instead of a sharp, inquisitive expression, the birds usually look dull and uninterested. Many can not even walk properly if liberated from these cage-filled warehouses. (Google "battery hens" and click on the images... if you dare.)

Yet - once liberated (should they be so lucky) instinct kicks in. The birds will observe other birds and start scratching, digging, sunning themselves and dust bathing within hours. Vocal and nonverbal communications between these birds is delayed at first. They often don't make the same sounds as chickens raised in a healthy, natural setting, but with time they do learn to communicate.

And just how smart are chickens? Well - studies suggest they are as clever as a toddler and learn new things quickly, given the right incentive. Need proof? YouTube is full of videos of people training chickens. Click HERE for a listing.

So - if you have read this entire article, give yourself credit for passing Chicken-Speak 101!

From Brooder to Flock Member - Integrating Chicks Into The Flock



How do you integrate your new chicks into your existing flock? Here’s what a few of us had to say on the subject:

Justine of Les Farms Says:

I integrated by having a run with little holes along the bottom just for the babies. They could get in and out, and the older birds could not get in (other than the Silkies - which was fine by me). 


It wasn't pretty, but it worked.. it worked really well.


This is on the outside. Chicks came through the holes and free ranged early.



Vicki Says:

My situation is different than most. I usually have broody's raising chicks so the flock is used to seeing chicks running around. I do not confine in a sense that most do.

Yes - I also brood chicks in a brooder.




When it is time to go outdoors… they go with the big birds.


They can get out of the building and they can get out of the fencing, but larger birds can't get in.

Then they graduate to another building when the next group comes.


They have access to the whole yard, yet can't free range yet. You have to be a laying adult and have the mental capacity to avoid predators.


The doors are kept open and all ages co-mingle all day long. I have about 20 food stations and 4 watering stations. My chicken yard looks horrible and messy, but it works for me. The adults are gone for most of the day eating out in the pastures, and the only ones inside the fencing are juveniles and babies. They all run through the 1/4 acre yard surrounded by a 7 foot high fence. I have 3 smaller fenced in side area's just in case I need to confine. We are presently working on two more. Next year I will have to confine more breeds to collect eggs and ship chicks. I added BCM to the Cuckoo. I also added the two varieties of Wyandottes.

Leigh Says:

While I prefer to have broody hens hatch and raise my chicks, it simply isn’t always possible. Hens don’t tend to go broody on command, and when they do go broody, they often all go broody at once. 


I hatch chicks throughout the season, and when I don’t have a broody, I have to use a brooder (mine is a large Rubbermaid container). When it is time for the chicks to start venturing outdoors, I set up my chick play yard. 


As the mother of 3 human children, I happened to keep 2 collapsible plastic outdoor playpens. They snap together to make one large yard which I set up under a big pine tree in the middle of the chicken yard. It makes the perfect cover to hide the chicks from aerial predators, and to deter my older flock members from jumping in to join the chicks.

 
This way my chicks can see and safely “meet” the older chickens though the plastic panels.

When I feel the chicks are old enough to fend for themselves (or run away fast enough) I let them loose as the flock free ranges. This can be a tough time because the older chickens will peck the little ones. Interestingly, I find it is most often the lowest chickens in the pecking order that are the worst about picking on the babies. I think it’s because finally these older chickens feel they aren’t on the bottom any more, and they want to keep those babies lower than they are on the pecking order.



Regardless of whether a chick is raised under a broody or in a brooder, they all have to go through a period of time where they establish themselves within the flock. This is the hardest time for us as humans to watch. Chickens are bullies - - but if we constantly intercede, the chicks will never become part of the flock. These are the times we have to stand back, plug our ears and not watch for a bit and let nature handle it.


During this intermediate phase, I allow all the chickens to free range together, but I keep the chicks in a large parrot cage inside the coop at night. I don’t like confining the flock in a small space together when there is still discourse. After a few weeks in separate digs (where they can all still see each other), the growing chicks are usually ready to perch with the older ones. In fact as I write this, two of my 9-week-old Swedish Flower Hen chicks are perching right up with the older flock members in the coop. 

So tell us - how do you integrate your chicks into the flock?

How Do Chickens "Do It?" Chicken Sex Explained



Well this wasn’t the post I had planned on doing today, but when I trotted outside with my camera to capture some artistic chicken shots on this glorious day, I was treated to a real lens full. Compliments of my Swedish Flower Hen rooster (yes – that is an oxymoron, but the capitalized part is the actual breed name) and one of his Swedish Flower Hen… hens, I found myself with the material for an educational course on the birds and the bees… with an emphases on the birds.

You know? This may seem in rather poor taste to post all of this, but if you are reading this blog, chances are you live on a farm or farmette, or at very least you have or want chickens. I think those of us who are farmers or farmers at heart realize that animals aren’t exactly shy about what (or who) they do or where/when they do it.

(Photo source unknown, but clearly brilliant!)
 So please consider this a warning. If you are easily offended or embarrassed, 

Stop Reading NOW!


*****************



If you are still reading, I will assume that you will not be offended or call me out for posting chicken porn on this blog. Further, I will assume you are either curious about how eggs get fertilized, or you simply can't live without knowing how I am going to approach this delicate subject in such a public manner.


As the mother of 3 children, it would be all to easy to start out with, "When a daddy chicken loves a mommy chicken very, very much..." 

But you know? We're all grownups here. These are chickens, not humans, so let's keep it real. 

It all begins with a hormonally-charged rooster looking for all the world as if he is using Joey's line from the sitcom Friends... "How you doin'?"


Then the Fabio side of Mr. Roo (his name is Gunnar) kicks in for the foreplay. If he could speak, I think it might sound something like: "Hello very fine lady. Do you see the lovely and flamboyant dance that I do just for you. I have lowered my shockingly well-formed wing so as to allow you to see my beautiful feathers. You are impressed, no?"




"Are you not paying attention to my amorous advances, sexy lady? Do you not think me divine?"










"Shall I share my awesomeness with you?"


And here, you can practically hear Astrid's exclamation of "Ooofff" as Gunnar takes a sudden and rather clumsy leap onto her back and balances with one foot on either of her shoulders.


The act that follows takes the balance and skill of Tom Cruise's character in Mission Impossible as he navigates some ridiculously unrealistic obstacle course of deadly laser beams that we all know were electronically added in during editing. (As an aside, I initially spelled "obstacle" wrong and my spell check wanted to change it to "obstetrical." Hmmm... very insightful for my little HAL 9000.)
"Watch as Gunnar delicately navigates this obstetrical course..."

Sometimes Gunnar uses his wings much like a tightrope walker uses a balance pole. Hey - it takes skill to stand on someone's shoulders while having "relations" with them... not that I would know from experience.. but... ahem - moving right along...


The above photo that captured the actual 2 seconds where the "home run" happened.



"When a rooster mates with a hen, he mounts her and, standing on her back, lowers his cloaca (vent) and the hen inverts her own cloaca to meet with his. There is no penetration, but the sperm packet released by the male is taken into the hen's cloaca or vent. From there the sperm makes its way to the infundibulum where it awaits the release of an ovum. Sperm can live in the infundibulum for more than 2 weeks."

Yeah - about 2 seconds is all the splendor in the grass that hen can expect.

Chicken folks will call this part "head-skating", "shoulder-surfing" or just "mating."
(And I call this postition, "The Vulture" he whispered softly into her ear as he fell off her back.)

That's right... shake it off!

A quick, post-coital snuggle...

"Quick! Act like nothing happened! Here comes one of my other wives!"

"I'll call you... "
And then comes the egg - though it can take a few days for eggs to be fertile after the first mating of a hen and roo. Also, eggs can be fertile for up to 3 weeks following the last 2-second romantic encounter between birds.


Even hens without roosters in the yard can go broody, but of course only fertile eggs will hatch.

"Look at me when I'm screaming at you, Mr.! First I push about a dozen objects larger then my own head out of my cloaca, and then I have to SIT here for 21 days! Did you HEAR that? Twenty-one days... while you... what? While you're off doing the wing-dance for that hussy, Ginger!"

And then come chicks!


And that, my friends, is where baby chickens come from!
