Yeah, you need to eliminate him ASAP. Ravens are smart and there's a lot of debate about just how smart they are. They would likely tell their friends about where food is, and I could see where 2 or 3 could take out a grown chicken.Nope, I promise it was the raven. I caught him stealing eggs, and I caught him killing all my chicks. Same as before, all gone without a trace, with the exception of one duckling he hadn't quite finished yet. That one he had just eaten the head off of, just like with the bantam Cochin. He also stole eggs out of my trap without setting it off. Since they're so smart, I have no trouble believing it was him that did it. To be clear, I literally caught him in the act of these things. Saw him doing it.
