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?
