Ok, building another aviary for exotics. Which last longest? for the top.Galvanized chicken wire or POLYETHELENE netting (not nylong)? Anybody try it longterm? I just did one in Poly net for my peacocks, but am also considering the Galvanized chickenwire ...it would take more tying together mundane work, but I could make the shape more to my liking. The nets often aren't the dimensions they give and I might want to make it differing shapes,etc. In the south, occasionally we can get 6-9" blizzards, ice storms etc. I have had 2" netting before...but these birds are smaller and am considering the chickenwire also because it is smaller diameter...
