My neighbor has a HenSpa with 3 chickens in it. If you're familiar with the HenSpa, it's a pretty darn solid coop. She had closed up the coop and went away for the weekend - they had plenty of food, water, shade, etc. Should have been fine. When she got back there was a symetrical appx. 15 inches by 5 inches rectangular hole in the tough green netting. 2 hens were missing, 1 carcass remained. The netting was slightly bulging out as if it had been pulled on. This animal would have to have been very strong and persistant. What drives us crazy is the perfectly symetrical hole, as if it had been cut with a knife by a human. Why would a human leave one dead carcass? Also we live in a neighborhood where the lake is in the back and people are never just wandering through your yard! I thought it might be a racoon - but again, the evenness of the hole!? Also, I've seen a coon around here one time in 6 years. We do have foxes, but how could a fox cut that hole?
