I personally think NOT. A white tailed deer could if it put some effort into it. But coyotes just aren't that big, or that agile to my knowledge. I admit that maybe a desperate one might attempt it--or a rabid one. I also admit that maybe one could try to climb over. But jump successfully a 5 foot high fence? I say "It cannot be done" My pen is about to be covered with 2" mesh top rite netting anyway, but I wanted some of your thoughts........ Thank you friends!!
