If it quits rainning construction starts on the new coop next week. I'm going to have sand in the coop and covered part of the run. To keep cost down we arn't putting a floor in. I can get rr ties free, so the coop will be on ties, and will have ties buried 2 deep, thats about 16-18". Will that keep anything from digging in? I've never seen a fox here, we might have a stray one now and then, but do have lots of coons and coyote, and the occasional bobcat and mtn lion. My biggest worry is the coons. I've thought about doing an apron also. Thoughts??
