I've lost just two. Both stepped on by the two broody's that hatched them. Two is too many. Every chick I hatch from this pen might be a contender for my F1 pen next year. My goal is to hatch 100 chicks from my pen #1. Only the best six females will be kept to go into my F1 pen (First generation). Only one male will be kept to breed back to the moms. Those resulting chicks will be contenders for my F2 pen. (Second generation) and on it goes in progeny testing. My goal is to have Silkies with excellent type, fertility, vigor, and health.Wow that's a lot of chicks! Its amazing the damage one little miss step from a broody can do. With three moms I'm surprised I didn't have more problems. I also have ground squirrels getting in the run right beside the run where the chicks are in the coop. I'm trying to trap them they're a big worry for me I would love to let them out in the run. I don't think the rooster would hurt them he seems to really like them looking at them on the other side of the wire. Whats getting yours?
