My Jap/D'uccle hen, who has been broody 3x in the past, did something crazy today. She was making 'momma is here' clucks, so I looked over to see if a chick had hatched. But what I found is momma pecking at the shell[where the chick pipped through] and them momma was tearing and eating the inner membrane! The veins were full and bleeding, chick was obviously not ready to pop out, no zip, either. Momma's beak was covered in blood, chick and shell w/blood all over. I quickly tossed momma out the coop, gathered all of her eggs and brought them into the bator. No idea if the chick will survive or not. There are other pips, 10-15 eggs total that she was on. Has anyone else had this happen? Is this normal? She has always been a good broody and great mom, never had her peck and eat parts of hatching eggs, though.
