I just went outside to check on the girls a short time ago and one of them was in the run dead. It's a totally enclosed so nothing can get in. And the sides are 1 inch wire mesh. I found her towards the front of the run and in the corner her head was facing in and on her. Not sure what happened. I think she was my broody one. Had one who the other 3 would not be bothered with at all. She would sit on the eggs before I could get to them and yell at the others to get away. Everytime I'd go out there she was always walking alone while the other three were going for food and/or water. They'd let her eat and drink but kept her at a distance. Could they have done this to her??? Not sure exactly when this happened but there was no smell yet. One of her eyes was gone and her lower beak was just hanging. I didn't see any feathers outside the run either. They are just turning 1 yrs old the 2'nd of September. She didn't show any signs of being sick either. I hope the others are OK and that it wasn't an illness.
