I currently have 3 pullets and 2 cockerels that are 3 1/2 months old and will be getting 2 newly hatched silkies sep 10th. I know I can't introduce the chicks till there around the same size as my other chickens but yesterday I adopted two little chickies from someone who could no longer keep them. One is a silkie pullet ( I think around 3 or 4 months old) and the other is a type of polish that is around 6 weeks old. The polish is still too young to go out with my flock. Since the silkie is big enough and I will eventually have to know what to do when my other chicks get bigger i was wondering how to introduce new chickens to my flock? I'm not too worried about my hens but I wasn't sure how the roosters will react to a new member of the flock?
