Chickens are flock birds - they prefer to live in small groups made up of one rooster and several hens, with chicks at various ages.actually chickens are not flock birds at all people say they are but I don't know why could I have some examples why you think they are flock birds because I have reasons to say their not flock birds .. flock birds stay more together and follow everyone but mine don't do that some of my hens follow the alpha rooster but that's normal because their his hens and they follow him every where but I have some smaller breeds of chickens and they stay by the barn and not follow everyone else they go down there sometimes but they like staying with some of the other smaller breeds and not following the roosters .. I have 8 roosters 16 hens and 3 ducks but most of my roosters have pairs and they don't mate with the other breeds a lot and the other roosters are a smaller breed most of them I have 4 big roosters but I am getting rid of one or two big ones but my alpha rooster is a big bird partridge chantecler and the beta rooster is a white bird I think a leghorn then the omega I think they are called are the rest of the roosters don't have much breeding rights they try to breed but the alpha or beta rooster kicks the crap out of them but each rooster has at least their own little fav hen .... so yeah I will stop yammering lol but I just want to have some examples please .. thanks ...

Evidence is found by the way they live in the wild - in groups.
They will roost together,
Forage together
Have a social pecking order
Have a lot of sounds to communicate with each other
Have social behaviours for display - eg rooster display dance, wing flapping, body language etc.
If they were not social birds then they would not have these behaviours.
If you have a lot of roosters and hens and different breeds, they will divide themselves into small groups, and each group will have their own space - this is what is happening with your birds.
