this is my 1st time building a run and I was at Lowes today and I saw metal deer fencing. I was going to put this up for my 12x12x6 tall run and then put 1/2x1/2 holes that is two foot tall around the bottom with a foot under ground so something would not dig under. Is this a good thing to do? Also I was going to use 4x4 post that are 18 to 24 inches in the ground. I might put chicken wire over the top to keep out things that fly. If there is something eles I can do let me know.
