I had 25 meat birds and now I'm down to 19. I have been finding 1 or 2 dead birds every morning with what seems to be cuts at the neck or thigh area. One of two things is happening. One a predator is reaching in a cutting them, or two they are cutting each other trying to stay warm or something. Has this happened to any of you. I might not have any left by next Monday. What can I do?
