I have a large coop that I have my three Silkies in (they are about 7-8 months old) They get along great aside from the odd "get out of my way" peck. About a month ago I picked up 2 Buff Brahma hens and put them in with the Silkies, but in less than a minute there was a fight so I took them out and made a large pen with chicken wire inside the coop thinking they may just need some time get to know everyone. I have tried a few times since to put them together but they still end up fighting, most of the time my Silkie's start it. Is this just pecking order sort of thing... not shure if I should let them get it out of their systems or not, just don't want any of them to get hurt. Is this normal when putting new chickens in a coop?
