Hello, I have an established flock of 3 hens and 1 rooster. This summer we incubated eggs and now have 3 chicks that are 5 months old. All day long while they are free ranging they are always seperate...I feed them mainly out of a feeder...the older ones attack during feeding, attack in the coop at night, basically any chance they get they are all just mean and one of the chicks got severely injured last week and had to recover indoors. What can I do??? I noticed today 2 chicks have pecked combs and are bleeding...I am at a loss on what to do...please help!!!! I just want a happy bigger flock!!
