Additional info to last question about my blue and gold macaw?

The macaws name is kodak and kodak eats the same thing he used to eat, except we feed him pop tarts, peanuts, or Graham crackers as treats and is only fed those three times a day. As far as the near cage/ away from cage aggresiveness goes, he doesn't get off his cage, and tore up a couple of blinds and a shelf. We have his wings clipped so he flies down. We have small dogs also. He usually gets out as much as he stays in, which I don't think he should. Also the tearing up the blinds isn't there a chalk-like block for that? We scold the bird, but don't shout cuz we know that makes it a game to him, although my little sister shouts at him when he screaches, which I'm tryin to stop, but she's kinda stubborn haha. I don't think he's ever had a bath although I'll have to ask my grandmother. The African Grey still has that feather problem, which I found is common in those birds, and the vet said that bird won't ever be the same. He is still with my grandmother, he was the old bird but is only like 40, which I've heard, for an African grey is relatively young. His last vet visit is unknown, I'll have to get back to you on that one tommorrow, maybe. Also at first he was really nice and then, overnight I guess turned grumpy, I'm not one to blame the bird and I think it has alot to do with him being moved, BY CAR in a twelve hour drive. But it could also be a cleanliness issue, which was one of my first concerns. Although we have a clean house. I've been trying to get my m to move him upstairs so he can see out the window, but she doesn't think it's a good idea. Honestly I think she's just lazy haha. Just kidding, but I love the bird and am hoping to keep him but the only way I can do that is get him to stop all this.
