Just to follow up. I have Vinnie's sweater but it's been too warm to need it. Like the harness, I'm opting not to put it on him unless we're actually using it, so I'm not sure how it fits. Neck might be a bit big while the body might be a bit short, but we'll see.
Regarding Vinnie's feathers, it's been over a week since he had the outer ones trimmed short. And I'm looking under his wings when he stretches and flexes, and everything looks good! Some of the smaller feathers are a
little ragged around the edges, but nothing is stripped! Vinnie's vet tech watched some of his videos on YouTube (
YouTube - Broadcast Yourself. ) and after seeing how he plays and bathes, thinks maybe he was just rough on those feathers. I've certainly witnessed him use his wings like arms to climb up perches and toys, etc., so it's possible that is what caused the damage.
Just wanted to let you know, I don't think he is chewing them -- at least not with his beak!
