Like I've said, when you leave exposed wood, they will chew the heck out of it! Another thing is that wire mesh should be made with stainless steel, they do sell that online. Another thing you could do is using plexiglass, that's how I made my walk in aviary years ago. My flight aviary I have now is made with plexiglass as well. You basically cover all the wood with plexiglass. When you drill plexiglass, make sure you have it laid flat before drilling and you need special drill bit or you will crack it. I used chains and hooks to attach swinging perches in different levels. I like my walk in aviary better as I can just walk right in and wipe everything down as the one I have now is a pain to clean since I can't walk in. The top of the aviary I used egg crate, stuffs that's used for commercial fluorescent lighting cover. Then I hang lighting above, it was really kewl. I wish I still had some pictures of it to show. It was not cheap to built! It was 8' tall, 5' wide, and 10' long. Maybe I'll build another one later on as I really starting to dislike the one I have as I can't really get everything as clean as I want it to.
