Hello! Hope you’re well! I have a 6-month-old budgie, Peetrie. His gender is unknown but we suspect he’s a male. He’s apart of a flock of seven; three other budgies, and three cockatiels. They do pick on him from time to time but I haven’t seen them done actual harm to him. We’ve raised him since he was 17 days old. He’s always been a momma’s boy but lately he’s been aggressive, biting us or peeping aggressively whenever another bird or us comes near. But I think it’s hormones, not going to lie. This isn’t my actual problem, though. He’s constantly bobbing his tail. I know people say that that’s a sign of breathing issues, but it’s sort of always been like that. I’d take him to a vet, but the ones here aren’t my choice of preference. They’ve told me he looks good a couple of months ago, when it was also like that. Peetrie is also a slow flier. You can sort of hear his wings clap whereas with the other budgies it’s just sort of a buzz. He doesn’t fly as high, often or as quick as them. And he’s breathing a bit more quickly than the others. I am a bit worried but I’d think he’d be very sick now if it was very serious. I’ve tried looking for help online but so far I haven’t had luck. Peetrie eats, drinks, flies occasionally and runs around. He’s anti-social, so he mostly hangs out alone. He’s only puffed up when he’s relaxing or sleeping. His beak grinds often, which I know is good. Another thing that scares me is that over the last...two(?) days I’ve noticed that he’s missing a few feathers above his cere. It might be the other birds but I really don’t think so. He has a few pin feathers on that area so it might just be that. Please don’t think I’m trying to use this forum as a substitute for a vet. It’s Judy the vets here in my area aren’t really avian specialists, and don’t do much. Unfortunately, I learned that the hard way. Please let me know what you think. Thanks!
