My girls need to get outside but we have run into some problems with the run. i bought a roll of 2" chainlink fencig for a great price. i have enough to do all the sides of the run and potentailly the roof. problem is that the geound i am trying to put my posts into is really rocky (actually bouldery, but i am sure that is not a word) so i canrt bury the posts down far enough for proper support. I can get down about 18" so my idea is to drive rebar in as far as possi le, set the posts over the rebar amd cement it in. But then i still have to dig the trench to bury the perimeter hardware cloth some places i can only dig a few inches before i hit boulders. any ideas about how to put down the perimeter wire. i am going to reinforce the chainlink with chiclen wire on the inside. does it need to go up the full height of the fence? Is there an alternative to the perimeter wire that would be as secure. i figure if i can't get past the boulders neither can raccoon.
