I found one of my soon to be 2 yr old GLW's dead on the coop floor this am. She showed no sign's of being ill in the days leading up to today. But there she was this am, dead on her side by the feeder. No signs of trauma either. No way for a predator to get into the coop & the other 11 coop mates all appear to be fine. She was one of my friendliest girls, always would push to the front of the door at night when I would close them up so she could get her nightly "feather ruffle" under her wings. I will miss her soooo much, this is the first time I've lost one of my girls...... I took her to the vet school so they can do a necropsy on her, hopefully they will have some answers as to what happened. I hope it's nothing contagious to the rest of the flock....I would be lost without my chickens!
