So its basically official... I'm getting an aviary

Okay, so it's not official YET, but I will know for sure on monday... did I mention it is FREE
I want to let my birds go fully flighted in the aviary... they'll live inside the house, but they'll go outside on nice days (only when I'm there). Bella and Tiko are really getting along Soo much better than when I first got them

And their learning how to pick their battles more wisely... its so great letting them play and only having to break them up occasionally... but back to my point.
DIMENSIONS ARE: 11' X 4" ACROSS (INCLUDES 3' WIDE SAFETY ROOM)
4' X 3" DEEP
8' X 6" HIGH IN REAR
7' X 8' HIGH IN FRONT
heres a pic:
It'll need some clean up and trim work... and I have to figure out how to cover the wood (because it's treated)... if they can't chew on it, it's not a problem right?
Another thing is Pacific parrotlets originate in Peru... I want to make the aviary somewhat like the Peruvian jungle (the amazon), what plants are from there that are parrot safe and smaller that 8ft?
This will be big enough for Bella and Tiko to experience some free flight, right?
Anything else (tips, suggestions...ect...) would be MUCH appreciated.
Thanks,
Micah
