I've read several posts here that say something like separate the roos from the pullets before maturity. One post said roos raised in a flock tend to be bullies to the girls. I've got 16 4 week olds, not sure yet the sex of any of them 100% (tho I'm making a good guess on some). When I know for sure, should I segregate them? They're for meat, so they'll only be here 16 weeks or so unless I keep one for fertile eggs. Is there some reason I haven't thought of?
