I have a flock of 4 bantam hens, that have been raised together. We originally had 2 roosters with them, but got rid of them because we live in an urban setting. The hens are now 8 months old. A couple months ago, one hen starting some really strange, aggressive behavior towards me! She comes at me, ready to fight, and jumps at me feet and legs. If i pick her up, she bites my hand, and holds on! I've tried putting her back in the run when she does this. But she comes out feistier than ever! It seems to be getting worse. I've heard of chickens taking on rooster like behavior in the absence of a rooster. Do you think this is what's happening? Ever had this happen to your chicks?
