It has been peeping for two days. The rest of the babies are hatched and eating already. The egg had hairline fractures from the hens fighting over nests so maybe that dried it out? I opened an air hole and since it was cracked it fell apart anyways, but her beak wasn't even close to poke out.
I took her from mama and put her in the incubator with high humidity.
I know not to touch if it's bleeding...but what do I do??
