We are converting a shed into a second chicken coop and quadrupling the size of our run. We will have 1/2" hardware cloth on the sides of the run to a height of about 8' so it goes up to the roof of the shed. My question is: is it safe to use the 2" x 4" welded wire on the top of the run? The chickens are always locked in the coop at night and we won't have any roosts close to the top of the run. Our thought is that even if a raccoon reaches it's grabby paws through the top of the run, it won't be able to reach a chicken. However, will they be able to bend the wire enough to go into the run? Just hoping to save a little money, but not if it means losing our chickens...
