I'm planning on moving my six chickens into a new inclosure. I live in an urban area but on a canyon. We have racoons, skunks, possums, a pair of hawks in tall trees in the canyon and a coyote with a den 10 feet from my fence. My chickens are currently in the front yard. High wall on two sides, wire roof, fenced in and in a hen house at night. Problem is the run is kind of small and I want to give them a bigger area. My back yard's outer perimeter has alluminum, pool fencing, re-inforced with 2x3" wire fencing 10 feet high. Within the yard I'm putting the 2x3 inch wire fence. I plan on putting netting over the whole thing, about 20 feet by 30. I'm less worried about the coyote but I'm more worried about the racoon and the hawks. Is there a spacific kind of netting I should use to keep the racoons and hawks out?. There are lots on black birds and mocking birds around. Will they bother the chickens or drive the hawks away?. The chickens will be in a secure hen house at night. Please, nobody suggest I shoot anything. I've visited other postings and realize people have strong feelings about critters comming after their chickens. Personally, I feel that alot of these predators are keeping the rodent population at bay.
