I've had a similar situation trying to help a chick hatch. There was quite a bit of blood so i stopped and put it back in the bator with a damp paper towel. Now ive removed most of the shell and membrane and the yolk hasn't absorbed fully. How can I help it? Is there any substitute for the yolk that i could feed it?
I don't think so. Do a search for duck in a cup. That part may help
