My 6 week old White Leghorn pullets got attacked to day. 3 got their tail feathers eaten, and 1 got a piece of it's wing eaten. Of of the ones missing it's tail died. I saw no sign of entry as far as digging. The only way they could have gotten in was to be small enough to fit through the wire. Any suggestions? I have no idea what did it. If it had been a skunk, or coon it would have ate more than just the tails.
