I need to build a run that is safe enough for me to go away for a weekend - we have hawks and foxes and probably racoons, too. I have even once seen a fisher cat. Sooo..... I want a 8'x10' run, and I think I will have to dig a trench all around it to bury the wire, right? It sounds like a ton of work..... and I suck at digging so the husband will have to help. We're in an old riverbed and its a real chore. but I digress. How deep do I need to go? Are there alternatives (besides a concrete floor for a run or similarly drastic measures)? What do you do? Also - people here seem to think that chicken wire is not enough protection from hawks. Why is that? What is the danger? Would a double layer of chicken wire be enough (still cheaper than hardware cloth). Thanks so much!
