I have 3 Buff Orps that are 5.5 months old. One of them is a cockerel, and if he stays as nice as he is right now, we might be keeping him. So far, we have brought in fertile eggs for our broody hens to hatch out, but with a rooster in the flock, we won't need to in the future. But, I have no idea of the relationship between the three buffs. I know they hatched together, so I have no reason to assume that they aren't brother and sisters; is that a problem if they have offspring? I am not planning on breeding them together on purpose, just wondering if I need to remove the BO's eggs from any broody hen in the future.
