Here's an update..... My momma hen has been sitting on many eggs from all the other chickens. Unfortunately, we did not mark them early on and a few more were laid during the first few weeks of incubation. 4 chicks have hatched, but one died within a few hours. The momma continues to sit on the remaining eggs. When and if she gets up before the others hatch, we were thinking of putting them in the incubator. Like I said we don't know dates, so I'm not sure we can figure out when to stop turning them. I figure they will die anyway if she leaves the nest, so it might be worth a shot. Anyone else done such a thing? Any help would be great!
