What a massive undertaking....I decided to clean the cage well and clear off the old paper scraps from the top. He didn't mind the cleaning too much, but he didn't like the paper theft. I swept up a garbage bag full of shreds. Kindling. But you know, in all that shredded paper an all the paper lining the inside of his cage there was no poop. I thought maybe he wouldn't poop in the cage because he hasn't been in it, but there's no poop on the top or off the sides. Maybe one on the papers on the floor in front. He seems to hold it for the perch across the room. That can't be healthy. Need something near he's cache he can go over to maybe. Maybe it's from living eight years with a steadily growing pile of parrot crap creeping up toward him...now he doesn't want to go in the cage if he can help it.
Anyway, since he doesn't poop on top I lined it with a piece of bookbinder's board. Way too expensive but it's all I have that's clean. He doesn't poop or eat messy food so it should last, and I'll find some corrugated board to put on top of that. He hated the installation! I had to fend him off with a half-chewed shoebox to do a final sweep and get it in. Gave him his chewed box back, he was still mad, gave him a cashew which seemed to help, gave him some phone book and he's working on that. Seems all is mostly forgiven. He's making the same snapping sound even with the cardboard. He must be snapping the lower beak against the inside of the upper, like someone snapping their fingers.
Next step will be to consult about the beak, see if he's lacking some nutrients. They are mostly keratin, right? Cant do anything about his bone structure but beaks grow all the time and there must be something to strengthen them.
