It's mostly eating them, a few die from attacks but aren't eaten. Lost all my roosters, and I'm really upset about one rooster in particular. He was a pet darn near. Let you hold him and loved being hand fed. Beautiful colors too. 3 weeks ago I had 28, now I have only 9. Been a coyote loose lately, killed one of my neighbors 20 cats. Can't say I'm upset about that. But like I said, wasn't him, no signs of entry, not that my son says he sees and I been gone the last month. I'm headed home tonight though. Thinking about buying some eggs, injecting them with poison, and leaving them out in the coop.
