I have a cochin that has 8 new biddies two eggs have not hatched I have checked them with a light I'm sure one is not going to. The other one has a bubble and is dark on one side of the egg. Should I give it a couple more days or just pull it. She will not leave the nest so I have been giving her food to eat. I know she needs to eat and feed the little ones. She is a first time mommy and doing great. Just would like to know what others would do.
