We have 17 Barred Rock babies and we were going to keep the 2 best roosters of the bunch. I found out that the man that we bought them from hatched them himself and he only had 4 hens and one rooster, so these guys are closely related. I don't want to have little inbred babies--should I be looking for a couple of able young men now or do I have a couple of generations before I see trouble? I gotta say though, I LOVE these little chickens. So friendly and happy.
