It was actually given to me by a local college. It is a walk in aviary. They ordered it and socked it into storage for years. A friend of mine knows them quite well and they offered it to him and he gave it to me. Its great and Jabba loves the outdoors. He is actually a lot bigger than I thought he might get and his casque is a monster. Its amazing to see him get places and not let it get in the way.
I built one like that out of PVC piping.... but tore it down because of not really having a yard to put it out on. One of the reasons I'm looking to move.'
That's very cool you have that and your cham will do great in it.
