I have 8 eggs under my Cochin and noticed this one was cracked early this afternoon. It's day 19 for this one. It wasn't the typical pip with a hole. More like she just pushed up a spot. I checked an hour ago and the shell was off, the outer membrane dry and separated from the inner, which was stuck to the chick. It clearly has blood vessels. I wet the inner membrane and stuck it under the hen. And suggestions on further aid?
