GD91, I don't know what to say. I'm sorry you've been bitten so much but I just haven't seen that in my group. Shadow is our fifth breeding buck, and neither he nor his formers were ever truly aggressive towards me, although sometimes territorial, of course. I don't think he's hormone deficient, he readily breeds with every doe offered, both mine and the neighbors. I think he'd even breed a sock monkey if given the chance. I've only been bitten twice, once handling a rabbit with a broken leg and once breaking up a fight between bucks. Ever since the latter I only keep one buck around.
