I've just constructed a very cute new house for my girls and am trying to figure out the run. The house has no floor and is located under some large trees. It would be really hard to bury wire a foot into the ground. Can I place the house on top of chicken wire to prevent predators from tunneling? Do I have to cover the whole floor or just the perimeter of the building? Can I do the same thing with the run? - have it sit on chicken wire? (I'm using 1/2x1/2 hardware for the sides). How about the top? I was thinking about using thick plastic deer netting. Should I worry about raccoons coming in through the top? Ideally, I'd like the girls to be safe if I went out of town for a few days and left the house open to the run. I'd appreciate any advice!!!
