Ok, I have a structure that is a roof and posts right now. I want to build off one side to make the 'coop' and make this the run. I would like them to free range most of the time but just in case I want to have all of the above. Question: I was going to put this up against the fence and put plywood or something along the back side and then put hardware cloth on the front so it is open. Should I do hardware cloth around the whole thing? Is it bad to have it against the fence for predators?
