Klamb85, here's a thread I put up with a lecture to vets from a vet on how to conduct a visit. They're focusing on birds with an acute problem, but it's still interesting. There's a funny part about being careful the small guys dont sneak out under the door LOL.
My advise is always to write everything down you want to ask or say since time is limited and you're usually distracted. I'd also suggest you talk a bit first, before removing her from the carrier so you can focus on what the discussion is instead of focusing on her. Like, tell the Dr your concerns if any so they can talk to you about it first then keep them in mind during the exam.
Also I'd advise you spend a large part of your visit discussing diet. If the bird isn't eating 85% pellets then they will want to know it and discuss vitamin and mineral needs. Well, even if they ARE eating 85% pellets they'll want to know it, too.
Finally, IME most vets are going to tell you what testing, if any, they recommend and they should tell you why. IME alot of people get nervous at this point but I think any vet will work with the people to prioritize what's "really" necessary at what time, and ongoing, if the people are budgeting.
Finally, it wouldn't hurt to ask about what to do and where to go in an emergency if this facility isnt a 24 hr ER, and also get them to advise you on what to do about a broken blood feather. If there's no AV around you you'll need to know how to yank one, or where to go to have it done, especially now since she'll be having a juvie molt if she's a baby, or perhaps a regular molt in the fall if she's an adult. It happened to my 5 mo old Parrotlet and he broke two wings next to each other, he was covered in blood and there was no way I could steel myself to do it. I couldnt get any vet around here, mine was out, and finally I took him to where I got him and they saved the day. But it was traumatic even for them since they were broken pretty low.
