Okay I have a pair of Zebbies in a somewhat medium sized cage, which I think is kinda tight. I don't honestly know the dimensions of the cage, but its medium sized. I plan on getting them a new cage a big one on a stand.

It's called the New-Bird-Parrot-Cage-Chinchilla-Cockatiel-Conure-Large. It is somewhat big, the dimensions are 32 inches wide, 18 Diameter, and 64 tall. I was going to put my Zebbies in there, and possibly? adding a couple Society finches. Or a couple other Zebbies. How many birds can this cage hold, and if you guys could possibly look it up? Its on ebay for 89.99. Thanks. I just want my birds to be comfortable, and somehow I convinced my mom a bigger cage haha.
