Speaking of nasty roosters, how about the young boys that arent really nasty but they cant get the hang of mating....they will just grab onto a hen any old place and then let her drag them around while she's screaming bloody murder. They don't court the hen to get her to squat, they just grab and it doesn't go too well. How long should you give those boys to learn to do it right or is there probably no hope when they start out like that?
