We recently received two girls (1 RR and 1 RRcross) and a roo from a friend. They are all older (18-22 months) than our current flock of 8 girls (19 wks) and 1 roo (7 months). I have them in separate pens so they can get to know each other, but I'm wondering about the roos. They are posturing and running at the fence at each other right now, though it's only been a couple of days since we got them. The new roo was picked on when he was small and lost his left eye. I'm worried that they will not get along at all. Should I keep them separate for a longer period of time and let the girls roam together sooner or keep them all separate and for how long? The older girls have layed since we got them, but our girls haven't started yet.
