Is this normal? This is my first time with multiple chickens. I have 3 Ancona roos and 27 assorted breed pullets. All are within a week or two in age (5-7 weeks). They have all been raised together, but now the lead roo, Stripe, has started wanndering around the brooder and harrassing the girls. They are in a brooding room (in the house) and have a pen that is about 5'x6'. They really don't seem crowded. The coop isn't finished yet, so they have to stay in the house a while longer (plus it's still pretty cold here, we had snow on Tuesday).
