Mystery footprint??

 When I let the chickens out this morning, I found a very odd footprint. First impressions was a fox, but I'm sure it's too big, it's about 4 inches wide!!!. Maybe we've got a Grey Wolf living out the back??. Does anyone have any suggestions? Neither ourselves or either of our next door neighbours have dogs.

The chickens are still not going out in the snow...I've had to shovel some away, so they'll come out of their houses...big bunch of wusses!

 The ducks and turkeys are fine with it, don't seem to make any difference to them at all.

Still, the sooner it clears up, the better...There's nothing worse than cleaning the houses out and coming back indoors with frostbitten finger tips!
