I have 15 chickens that are all almost 6 months old. 2 are male. these are my first chickens. I have questions about my dominant roo: I've heard about mating dances, but I don't think he does that at all...he just chases them around, grabs feathers and goes at it. they don't seem to like it one bit....Is that normal? He is not mean to my husband or I but yesterday he attacked a friend that was visiting. I wasn't around to see it, but evidently waited until the guy's back was turned and tried to spur him. should I get rid of this rooster?
