I am starting to construct an aviary over the outdoor run. It started with some plastic poultry netting and metal stakes. It has now blossomed into a 10 foot high aviary that I'm constructing out of red cedar trees that I cut down and removed all the branches. I Cut them 100" and used the thicker pieces cut from the bottom for the uprights that were screwed to the metal steaks. Well anyway my question is, does anybody have an idea as to what can be used to cover the top? Some kind of netting perhaps?
