Sorry, but keeping the birds in the house could never work. He has about 20 breeding pair. The birds have inherited my covered carport and the cages are also covered on the tops and have shading partially down each side which protects them from the weather and sun. Since the flooring is concrete and each cage stands about 3 1/2 to 4 feet off the ground, we are able to clean the area quite well each day. I probably should have mentioned all this earlier...sorry!
