My chicks were due to hatch this past wednesday. We had a temperature drop in our hatcher and have had 1/3 of our eggs hatch. I candled them a few minutes ago and 1/3 of the eggs were way past dead, like should never have been put in the hatcher (really need to get in the habit of candling before putting in hatcher). Anyway, the other 9 eggs are filled with chick, just not sure if dead or alive. My hubby opened the air cell of one egg and there is a what appears to be fully formed chick all curled up. He did not break the membrane as there is some veining. I dont know if it is alive or not, what am i looking for?
