I have 12 chickens that are 8-9 weeks old all together. Pullets: 2 white leghorn 2 buttercups 1 australorp 6 cochins I am unsure of sex 1 australorp cockerel The Australorp is HUGE....and pretty mellow. He just does his own thing. Hasn't caused any big problems......I catch him every day, morning and night and he doesn't peck or fight or anything. Today I was catching everyone to put them away (they spend the day in a pen outside and the night in the shed in the garage until their coop is ready) and one of the pullets was throwing a fit when I grabbed her....just squawking and carrying on.... And Mr Australorp cockerel came up behind me and grabbed me by the arm with his beak. Left a big bruised welt on my arm. Ouch! Now, on one hand, he is usually nice and was just trying to protect one of his "ladies". On the other hand, I am the boss. I ended up whacking him with my arm and then stomped around after him...picked him up and held him for a while (he was not bothered by the holding at all) then made him "stay away" while I finished catching all the girls up. I always catch him last. He is actually the most mellow and easy to deal with of the whole bunch......and has showed no aggression up until now. I understand why he did that but am not sure how "aggressive" to go after him for doing something like that? I like that he is protective of his girls, but I assume as the "head rooster" he should defer to me doing whatever I want to the girls, right? I also have two RIRx that are about 11-12 weeks old that are kept separately, 1 pullet, 1 cockerel. That cockerel has been mr attitude from day one and has grabbed me by the hand already and postured at me, made crazy rooster growls at me and threatened to come after me (and then crowed, the little jerk). I whack him if he comes at me....he gets caught morning and night as well, but I have to catch his pullet first.....and then he freaks out and tries to get to her and I can grab him. I'm pretty sure he will live up to his name (crockpot). I know I need to be "the boss" of the roosters......but not sure how "aggressively" to respond to the nice ones that are just protecting their girls?
