I have a broody hen who was sitting on 8 eggs, 7 of whom hatched yesterday/last night. The 8th pipped this morning. Mama hen moved earlier this afternoon and at that point there was a hole big enough to see the chick's beak and so I put the egg back under mama, just went out there and the chick is #1 still alive, chirping and breathing...but it almost looks like it's shell has been pecked off. It isn't in the typical zip pattern, and there is some blood, not a ton. I put it back under mama but not sure what I should do. Should I try to save it? Just leave it to hatch the rest of the way on its own?
