I have one older chick who was getting quite lonely and starting to think she/he was a human. I have recently bought 4 new chicks about half the age and size of the older one. We have them in separate pens because the older one was pecking the younger ones. Right now they are in a place where the older one can see the younger ones if she/he is on her/his perch. Almost everyday we take them out, set them on a cloth and put their food out there and bring them all out together. The bigger one still seems to pick on them. Will she/he just get used to the younger ones or will they have to be separate for their whole life? (Being separate won't be a problem if it turns out to be a rooster because he would just go to another farm.)
