I have 1 bantam rooster who is pretty easy going and 1 bantam hen and 1 plymoth rock. My rock picks on my bantam hen and is clearly the Top hen. Anyway, my 4 week old chicks, (2 cochins, I think, and 4 red pullets) are currently in a coop next door to the older ones. I have no idea at this point whether my cochins? are hens or roos. When is it time to intermingle everyone and will my bantam rooster be okay with the new girls? I'm also afraid that my Top hen will be pretty mean to the new girls when mingled due to her pecking at my bantam hen. I let the older ones out to free range a couple of hours a day when I am home, so I'm wondering if I should let them out to free range with the 2 yr olds when they are ready which I'm gathering is about 8 weeks old. Any experience or suggestions are welcome. Thanks!
