It was my fault, I made the "***"umption that they would be ok after they got as big as they did. I personally watched hawks circle overhead, while I was out of site, and they move on because they didn't want to tangle with them.
My 5 acres lot is fenced and have not had any large animals on my land since it was completed. The back half (not fenced by me) used the cheap field fencing that has larger openings. maybe 10" square.........
The kill site was by the field fencing on back portion of lot. That's what leads me to believe it was a land critter. But not sure what would have got the jump on him that would be able to lunge through a 10" square and then be able to either eat him entirely. or take the carcass away after making such a brutal mess.
All though feathers were scattered in a circle I did not see any big blood spots, or spray or anything, just 2 or 3 pieces of meat attached to feather chunks.
The circle pattern has me wondering if it was a dog. just thinking about how my little dog plays with the toys by shaking it back and forth in her jaws.....
The only thing that resembled tracks was just on the other side of the fence two deep holes spaced apart just right for a pouncing animal of some kind. But they were very small I was thinking fox but I don't think they hunt at night, do they?
