So sorry for your loss. I recently had something get into one of my, what I thought was a secure pen. It got past an electric wire that was out further than the rest of the wires and plowed through the wire on the top part of a gate and all birds are missing with no trace. I think either coyote or fox. I did notice some tracks out there this morning when I went out to check my cameras and birds. A camera was set off but unfortunately it was very foggy out so I couldn't see what set off the camera. I have seen both a fox and coyote around. Good luck...
