I have a combined chicken run and garden which is divided in half. I've installed 8ft woven wire deer fencing around the entire 32X72 area and cross fenced the 15X40 run along with the 8ft woven wire deer fencing and 3 ft chicken hex on the bottom. Then realized the gaps in the deer fencing, above the 3ft chicken wire were too large and so I added the 8'X 1" square black poly deer fencing in addition all the way around and on the top. Good grief...talk about an expensive design error. I hadn't envisioned 3 layers of fencing would be needed, not to mention how downright ugly the black poly deer fencing is. My goal was to keep the birds safe from any predators (including my dogs) and the chickens and deer out of my garden. Now it looks like some sort of military or US/Mexico border line just without the razor wire. (gee...I suppose I could add that to the top?) Do I wait for a predator diaster to replace it all with hardware cloth or do you think my Fort Knox will be safe?
