I had a Silkie chick hatch under 1 of my broodies yesterday I heard a bunch of loud peeping and went to check thinking one of the older chicks was stuck or being picked on and there it was. Sitting in the middle of the coop floor peeping its head off. I checked my sitter with the oldest eggs and they look to be on day 14 or so, but the shell was under her. I have NO idea how that happened?
