Just wondering, but don't broody hens set for a few days after her chicks have hatched? My Welsummer had 11 eggs under her, 5 hatched, and as soon as they were up and about she got off her nest and left the remaining eggs. They cooled for about 24 hours... think they're dead? I tucked them under my other broody hen, just in case there was a chance they might be able to make it. Any ideas on what the odds might be?
