Regardless of what you have, you may have to be proactive by covering your bases, what ever it is likely to be back. My thought is set at least one Live trap large enough for at least Raccoon size, set several Victor Rat Traps w/ meat bait in Cubbyhole/box like paint can size or wooden box around the periphery for Weasel, & trail/game Cam if you have one. In other words, set up a Gauntlet & hit them hard. Raising stock , birds, vegetables is tough business, so many things out there want an easy meal. Best of luck & so sorry you have to do damage control.
