Ok so I bought a pallet of bricks and I am starting to build my russain tortoises enclosure. It is almost eight feet long and 3 feet wide. The problem is that near my house, there are many red tailed hawks. Actually the other day I saw a mouse running across the street. And right before my eyes, a hawk swooped down and took the mouse. I was only about 8 feet away so it made me wonder. Is my little russain safe outside? Are there any ideas of how to make a large lid for a brick enclosure?
