I have my first little roos. They are only 13 weeks now. I know they go through a wacky hormonal period and are not so gentle with the girls or each other. How old are they when they're personality is pretty well set and you can tell who is going to be mellow vs aggressive, good with the girls vs rough, and the like. I have a little d'uccle that seems to be a little sweetie right now. Doesn't object to being held, not rowdy with the girls, just stands up to the 2 silkies. He is the one I'm thinking of keeping right now but one of the silikies is a watchful little guy, always standing guard for the others, letting them eat first, but he is a bit rough with the others (he is head of the bantams right now). He will posture at and run behind my DH so he may end up being a naughty one.
