I thought that my chickens my be prolapsing, then I thought that a predator was getting into the coop, but then I realized that they are pecking each other to death. I have lost 4 chickens to what I think is vent pecking....I find them dead with gaping bloody vents! I checked my other chickens and a couple of them were missing lots of feathers and had peck marks near their rear ends. I sprayed all of them with blue-kote. Is this something that I need to do regularly? Is there anything else I can do to stop this habit? What kind of things can I give them to keep them from getting bored? Thanks so much!
