I have a cockerel that is about 16 weeks and younger pullet that is 11 weeks old. They seem to get alone and stick together. I also have an older pullet that is 20 weeks old. The cockerel is afraid of her and runs away when she comes around. The cockerel is only a little smaller than her and a little younger. She is the dominant one in the pen but she isn't chasing him around. However, I am afraid that he will grow up fearing her and not mate with her when they come of age. Should I remove her or let him get older and reclaim dominance when he is ready to breed? At least the two younger ones give each other support. Need some advise please.
