I have 9 chickens total, 8 pullets and and for sure one cockerel( I am beginning to wonder if my NN is boy too or just a dominant pullet) anyway, when I first got them I had them all in one brooder. As they got bigger I had to separate them in to two brooders. Now they are in their coop and they stay with the same groups that they were in the brooder with. They have been in the coop for a little over 1 week. Even when they are in the yard they stay in the same little groups and don't interact at all. Will this change with time or will they always segregate themselves?
Thanks for asking this question. I am wondering if my 4 little groups of chickens will ever get together. I have 2 EEs and the 4 mutts together in a pen (same ages I think) and Millie and the Delawares are all together free ranging. The last pair are beginning to socialize other than just pecking. When they hang out under the car, the Dellies will be in a little group and Millie will be separate. (They've been together for 2 weeks). And in the pen, the EEs keep to themselves for the most part. They are starting to integrate some though. Looking forward to hearing what the chicken gurus say.
I integrated mine a couple of weeks ago, and they are starting to interact. They range together fairly often now, although they still separate sometimes too.
