I have a chick that seems to be full grown. My darn hen has decided that she is done hatching her babies. She had 2 eggs left that haven't hatched yet. I candled and didn't see any movement. I just figured because they were cold for so long that they were dead. When I opened the shell....IT'S ALIVE!!!! So now I have them in the bator with a wet washcloth covering the one with the open shell. Is it possible that it will still survive?
If in fact it has not reached its hatching date, and the part where the shell is open is not incredibly huge, you can apply some tape to close it up. It should live though if you close it up and you have not disturbed the living embryo.
It had not pipped yet. I figure that it had about 1-2 days left. It was barely moving when I first opened it. Now it's moving like normal. It was so cold. I held it infront of a space heater for about an hour (with a thermometer) until I could get my bator warm enough. I'm going to check on them now. Keep your fingers crossed.
