Sick Budgie(?)

[Friendly Feathered Friend]

My 2 year old male budgie Sparky is having some kind of health problem. He woke up this morning wheezing and struggling to fly. When he does fly, he always crashes into something, when he is usually an amazing flyer. He also makes a sound when he flies that makes it seem like he’s having trouble breathing. I got some Pedialyte into him in case he’s dehydrated, but he didn’t really like it. I cleaned his dishes and got him fresh pellets and water with a few ml of Pedialyte. He doesn’t seem to want to eat anything except millet, when he usually has an incredible appetite. He’s also a little puffed up, which tells me he may be cold. I’m definitely going to call the vet tomorrow, but in the meantime, what can I do for him? I’m afraid to let him out of the cage because he flies a lot, and I don’t want him to crash again. Here’s what he does every time he flies. Excuse my messy room, I will be cleaning it very soon. You can also hear that he makes a clicking sound when flying.
