I just got chicks a few weeks ago and am working on the coop. We live in Indianapolis and see occasional coyotes, hawks, and racoons around the neighborhood. My coop will be inclosed and secured with a 360 surround. I am digging a trench for 1/2 inch hardware cloth and placing it under the coop as well. We plan to take the 1/2 inch 36 inches up the sides. The coop is about 5-6 feet tall. Our question is, do we take the 1/2 inch all the way up or do we stop and 36 inches and do a less expensive hardware cloth on the top half of the run? It will have hard plastic roofing. Trying to save cost where we can but don't want to do make a mistake either. Thanks for your help!
