I know that cockatiels are a dusty species of bird, and I think I remember reading that it's because their down feathers disintegrate into dust or something like that. But, I've never seen any discussion of the amount of dust they produce, and I'm curious. Just how dusty are they? Are some dustier than others? If when I get my 'tiel, I give him a shower every day and drip some aloe vera on his back from plants I have, will he still be dusty? Is it possible to bathe a tile too much? My 8 year old sister is so excited about me getting a bird, and she has some allergies, and I really don't want to have yet another pet that she can only look at. So if bathing him would help, I'd be all for it.
