All 7 of my broody hen's chicks where fine in the morning, but when I went back out there a few hours later, under her were two chicks with bloody beaks. they where twisted, and one almost conpleatly missing. One chick is missing, but all the others are safe and happy. My broody runs around with all of my chickens, and this is her 4th batch of chicks, raised the same way. She is super protective, chasing and pecking anything that gets near her, and she almost kiled on of my hens that got to close. What could of happens? what can I do?
