I have a run with 5 older hens 2 older roosters I think in my rooster/hen ratio is way off some of my chickens backs are bare. I have some 13 week olds in another pen. Can I move them over? Also I have a mom who hatched 3 babies about 5 weeks ago in that own too. Can I move her over with the other two in the bigger flock? The 3 babies will be left with some 9 week olds. Will that be okay ?
