Hello and Welcome to BYC.
Good luck with your search for property! Not sure what predators would be in that area. Hawks, owls and coyotes to be sure. Do you have any knowledge of what else might be out there?
I like the 3 walled design myself. We live in Phoenix so heat is an issue here, hawks and owls our primary predators but opossums and raccoons are possible. Our coop is walled with 1/2" hwc on the front. We have the option of closing off the front with wood panels when it's cold, but can leave them off most of the year.
