Please tell me how to stop my hen (Black Cochin) from killing the chicks as they hatch! The first egg hatched and she became a wonderful mother. As each subsequent egg has hatched, I find the chicks dead. After finding the first two dead, I assumed it was natural causes. The next three I found on the floor of the coop with heads missing, shortly after hatching. Next one, I arrived just in time to rescue the chick before the mother got her and I am raising her inside the house. One egg was not yet hatched. I have it inside, keeping it warm. I took the 2 day old chick in to the coop to see the reaction of the hen. upon spotting the chick, she immediately tried to attack! Why is this hen so agressive to all but the fist one hatched? Will I ever be able to integrate the baby (that I am raising) in to the flock? Please help!
