Hi, I live in Roseland, NJ, where we are allowed to have 3 hens for eggs only. Recently we were on vacation and the person who was feeding my chickens came across 1 of them dead with her insides eaten out. My coop is a shed with a chain link fence for a run. It has a roof and is lined with deer fencing as well. If the dead chicken was the weakest of the three, could the other two possibly do that damage to her or should I assume a predator somehow managed to get in? It isn't easy, and I've only seen small rodents like chipmunks sneak in to steal seed on the ground.
