I've posted before about my crossed beak chicken Amelia. We found her in a nesting box this morning and her head was gone. All other chickens are fine and their is no sign a predator git in. Did my other chickens kill her? If so, why? She has been in the flock for months with no issues. She's not even the bottom of the pecking order. Ten chickens have a 6 x 8 coop with 6 nesting boxes and places to roost. They have a 25 x 50 run that I put tons of things for them to scratch around in. They always have food and water. As far as I know she wasn't sick. She was her usual feisty self yesterday. Why would they eat her head?
