3 or 4 coyotes would clean it up like that, in a short amount of time. They will eat as much as they can and go puke it up away from the carcass (like a fox does) and go back at a later date to eat their puke. I have seen 7 coyotes completely clean up a 1300 lbs cow in 5 days.
Here's a man that knows coyote behavior. They will visit that carcass several times per night eating all they can stuff in, then puke it up in a secure location for later consumption. The coyote version of a dog burying a bone.
