Cool pics. I'd probably go ahead and take her. Gotta believe the coyotes would make short work of her sooner than later.
I've seen the same 3 legged coyote 4 times over the past 2 years by my work. Looked like its eating ok even tho it lagged behind the other 2 it runs with.
Same here a long time ago on a drive. It was a buck though and he had no problem covering a lot of ground fast.
