I have 2 roos (cockerels really) and 10 pullets. One roo started out soooo mellow, but now is a big meany. He likes to rip holes in the heads and combs of the females. I know when they are young (he's 4.5 months old) they are akward with mating, but I think he creates a weakness on the pullet, then exploits it. They are getting really messed up. The other roo sort of chases him off at times, but at other times JOINS him. My question is, should I cull the offensive roo in question or should I wait and see if his disposition improves? Once they taste blood, are they ruined for life? I could eat him, I have no problem with that. He's just sort of a favorite gone bad, so I am looking for some alternative ideas. Thanks!
