that's what's my money is on!She said they don't have any close she would have to do it herself.
I think you should get some kind of game camera set up to video their coop, run and surrounding area.
It sounds like either a predator attacked and then took off or your neighbor did it. Probably your neighbor. I would put up a game cam or even a couple of them to see if you can catch her in the act. Some people hurt others to feel better about themselves and she sounds like one of those people. I'm verry sorry.
A necropsy might help, but my guess would be that she grabbed your drake and broke his neck. He would have been fighting for his life, thrashing and screaming, which terrified the rest of the flock.
I really hope this neighbor leaves you alone now.
Please keep us updated.
