We're about to build our first coop (chickens arrive in two weeks!). For the run, my husband plans to dig about a foot down, bury chicken wire, and use that for the sides and top too. Will that be enough to keep animals from digging their way in? The wire will be recovered by our local dirt/sand. For the coop, he'll put in a wood slat floor over the current dirt and will do wood walls and ceiling, but wasn't planning to use hardware cloth in the walls. Would you recommend we put that in, or something else, to keep the mice out? We have tons of mice here in the high desert of New Mexico. Thanks!
