I hatched 39 chicks that live in a super big coop. I noticed a few fights amongst them & woke up the other morning to find one chicken dead. Looked as the flock pecked one chicken to death. The flock is around 5 weeks old & seem very healthy & active. I did open the chick up thinking maybe she had worms but none were found. She/ he looked to have been pecked around her neck. Just curious if this has happened to anyone else. I've never experienced this before & have three different flocks. Guess it was their pecking order that caused the death but not entirely sure.
