I am a new chicken momma. I have 8 pullets and 2 cockerals that are 5 months old all raised together. One cockeral has been trying to mate with the girls, pulling their heads and tearing out a few feathers They seem afraid to come out of the coop in the morning and stay up high roosting most of day. I feel like they are trapped. The cockerals hang out below them on the ground strutting around and eventually join them to roost. Should I remove this one cockeral or is this normal behavior? I feel like my girls are not able to relax and feel free to peck around.
