I walked into the coop today, and it sounded like a wild animal had gotten into the coop and was eating a chicken alive! I rushed in and the second part was true- but it was getting eaten by another chicken!!!! It was chasing her around the coop, trying really hard to eat the feathers. Several (All?!?!?!) of my chickens are doing this. I am so helpless I am ready to cry! WHY are they doing this and WHAT can I do to STOP IT?
