I have a nice big grow out pen/tractor (8x20) with about 30 babies in there. They were hatched on 12/21 so about 6 weeks old. Assuming a 50/50 mix i must have 15 boys in there. Counting them is not easy , so i just estimate. Just today I started noticing some little baby fights going on mostly between the boys and i realize that as they get bigger I'm going to have an issue. So.... I'd like to wait until they are about 5 months to decide who gets to stay permanently to make nice babies and go into a separate pen with prospective moms. At what age do you think i will need to separate them from the girls so they don't fight? and if I build a batchelor pad will the excess boys be ok in there by themselves? I had hoped to just keep everyone in one pen until they were ready but now i am thinking that won't work?
