Hi All! I'm new to BYC, and am hoping to find some advice here... I have an extremely critter proof chicken coop, but am in the process of trying to add on an exterior run for my girls. I live in a region that has plenty of predators interested in my girls, and have a chain link dog kennel handy for conversion. Can anyone guide me in the right direction of making this safe against foxes and raccoons? I know that I need to add a roof to the kennel... but also need this roof to be capable of handling a snow load... suggestions??? Thanks in advance!
