To keep coyotes out, you’d have to have SOME kind of fenced yard. I’ve read that coyotes, which plan and scheme and strategize for weeks, can breach fences that most humans would assume were completely coyote proof. The fences on the ranches where women kept their toddlers “safe” while carrying on their busy workdays were high enough to keep the kids in and did the trick because predators like coyotes and big cats, which could easily navigate a four-foot picket fence, were SHOT AT ON SIGHT always and kept their distance well from the main house during the day. Fences sound nice ... but won’t do the trick unless you make them eight feet tall. SHOOTING TO KILL the predatory animals will do the trick.
coyotes can jump a 7 foot tall fence.
