Ok, so I'm trying to comprehend how much dust can 10 birds put out. They're, oh, 4 weeks old or so and still (been raining, had flu, etc) living in a huge dog crate beside my desk. I'm wondering how much dust is because of them (wire floor) or if I can blame some on the guinea pig who's to the OTHER side of my desk. It's a good thing I don't have allergies. At any rate, over four days (I laid a book down and left it) there is a nice visible coating of dust on it. So.... How on earth are they so dusty?? Is it ALL dander from their feathers growing in? Do they like, sweat dust? What's their secret? I wonder to myself if Charlie Browns "Pig pen" was related to chickens.
