Hi there, I have 12 chickens, so far 4 or 5 Roosters and the rest are pullets. The biggest rooster (sex linked) is very aggressive to my two white sex linked (not sure what you would call them...we are new to this) today he bit and held onto a comb of a RIR, she was screaming..it was pitiful. What can I do? Pretty sure he is the top chicken in the coop as far as pecking order is concerned. any info is appreciated!! Thanks!
