I'm building an aviary for a pair of peafowl, which I do not yet have. It will be about 30'x30'. The top will be about 10' to 15' high amd covered with a net with 2" holes. The sides are covered with what we call "turkey wire", a welded wire net with 1"x2" holes. It will contain an open shed, a large open area of sand, an area of stones and rocks, several bushes and a few large branches, and a space of about 15'x8' which is a crawl space under a deck (about 30" high). I'd like to keep one or two additional species of hardy birds that might be compatable. Does anyone have experience and advice? Thanks, Jerry
