60x40 Foot Aviary

[FF218]

Hey,
One day, If I make enough money, I hope to re-create the 'jungle' habitat [similar to the shyne foundation only more elaborate] for Macaws that people dont want anymore. I read an article saying that for a Hyacinth to sustain flight the Aviary should be at least 50-60' long and 30-40' wide... So I would try to make it as wide as possible but lets just say I went with a 60x40 Ft. Aviary. How many Macaws would fit comfortably? Any ideas about this? Bad idea to house the birds together? Remember ALL birds would come from Shelters and from homes where the people coulnt care for them anymore (its too loud, doesnt preform like they thought it would, is not pretty anymore because he plucks his feathers etc.) My purpose is to try and give these guys the space they deserve and get them closer to their natural habitat.
Thanks for the help

P.S. I was thinking about putting in a Sprinkler system that withdraws into the roof so the birds couldnt get past them...This would allow for watering of the plants and giving the birds a nice rainforest shower ;) The Aviary would be indoors but I was thinking about doing vents that lead to outside that I could open and close just to let some fresh air in. Also I was thinking about putting in speakers [of course not where the birds could get to them] and play one of those rainforest CD's... maybe even go as far as dimming the lights a little and playing a thunder and rain CD [not to loud, so I dont scare the birds] when I turn on the sprinklers....
opinions?

Im gonna put this in the Macaw section instead so if someone could delete this?
