I am planning on making an outdoor enclosure for my tortoises. I will always go to great lengths to protect them from wild animals (there are lots of raccoons where I live) and I want to use chicken wire or some other alternative to cover the top and bottom of the enclosure. Now I have one last problem I need to address - How am I going to access the inside of the enclosure? I can't put a hinge on a huge enclosure like this and just make the top a hatch. The enclosure will be about 16x16 feet (~15.8x15.8 on inside) and 6-8 inches walls.
