Day 21 was a complete nightmare. The fan went out and the temp dropped like a rock, along with the humidity. Three chicks hatched and a forth tried for almost a day, before I broke him out of his shell. The first 3 pics are my new babies...the sweet part of the hatch. The last three are of the chick that is barely hanging on and may not make it and of the chicks that I removed from the eggs on day 24. It appears that they were fully grown and the yolks were moving inside, but then it stopped. downed? low temp? What would cause this?
