I am looking on http://www.southernstates.com/catalog/c-1578-fences-netting.aspx for hardware cloth and fencing for my coop and run. I know that I will use hardware cloth for my vents in my coop just not sure what gage. I am also converting a 10x10 chainlink dog run into a portable run for my chickens (they will also be allowed some supervise free ranging). I def want tighter weave wire for the bottom 1/2 at least of the run, no chickens out and no larger critters in. I plan on the hens being in the coop at night to keep them safe from predators and being in the run or coop durring the day. I dont think I need overkill as most predators will not try to harass them much during the day. is 1/2 way up the chainlink with tighter fencing ok? I will do an apron along the bottom too just to discourage anything trying to dig in. I will be doing aviary netting or something similar on the top of the fence to keep out our resident hawks. I even thought about doing wire all along the bottom of the run, but think that might be unnecessary and hinder the hens scratching ability. What are yalls thoughts?
