I have a hoop house tractor/coop that I have been using for a few months. It has a wooden base and cattle panels covered in chicken wire. The problem is it is EXTREMELY heavy and difficult to move. I am considering using about a 2 inch PVC as the frame instead of the wood. I thought this would make it lighter and easier to lift and slide. My question is do you think this will be too light? I have an outstanding livestock guardian dog that has kept them safe so far. I have lost a single bird to any predators. (Unfortunately I lost a sickly, blind turkey to my 2 year old and 4 year old who were "just giving her a bath"). I just wonder if I use a PVC frame will that make it easier for predators to get into the coop? I have a lot of raccoons, coyotes, and possums in my area so I want to be careful and make sure they wouldn't be able to dig ad lift up enough to get under it. Any thoughts or suggestions?
