We have some chickens that are a few weeks old. We call them “teenagers” bc they are almost all feathered now. We had 5. This morning I went to feed them and there was one chicken that was dead. Her head was gone but her body was left. They are in a wire cage. I will show a pic. What could kill a chicken in a cage and only eat it’s head? Sorry... gross I know but seriously, I am stumped.
