I have 10 bantam chickens, 2 of which are roosters and they are about 6-7 weeks old now. They have always lived together and all of a sudden one of the roos (silver sebright) is acting like a total maniac to one of the hens. He pecks her, chases her, flies toward her and this evening I found her with her head hiding under some straw! I think she was scared!!! Is this normal and should I take him out? Help please. Thanks everyone!!! One more note-I did recently giver one other roo away to my FIL. Could this have something do do with it?
