My little chickens are like their own flock, but I have older chickens 3 1/2 to 6 1/2 months old. The little ones are about 2 months. They were pecking at the little ones last night and I don't think they knew what was going on. I wasn't sure if its pecking order or they just hate them. Here is one of the little ones. We think she is a silkie. Here is one of the middle aged ones. She is a golden buff. Here is one of the older ones. She is a white leghorn.
