I have no idea. I just read the whole article about which predator it could be. I saw a dog trying to get in the other night, but it was digging. I then secured my chicken tractor with more chicken wire around the bottom - laying flat around the edges. Then two nights ago something got in and ate all their chicken scratch but got caught on my excess wire and left bits of fur - kinda greyish brown. Then last night - I looked out at 2 in the morning to see both water and food dishes knocked over - and 1 of the 4 chicks missing. He seems to have just disappeared. There seems to be no exit and only 1 feather - which frankly did not look like my chickens feather. The only thing I can think of is something stuck it's head under the netting I did not have too tight over the top of chicken tractor. But that would have required a lot of thought, in my opinion. It would have had to duck its head under it at a level of about 3 feet. Yikes
