As a former parent of an epileptic Robin, I can say that vet care is NEEDED. Like, so, so, important. I was not able to get vet help for my Robin at the time, and she passed during her third seizure. I was heartbroken. But, I was also 11 (although I did quite well and hand-raised her with no experience from day 3). I didn't know about online vet consults, and it hadn't even crossed my mind to look into vets 2 hours away or more. Now, I'm slightly older, and I can give you advice from my couple years of budgie parenting, regarding vets.
1. Online consults are better than no consult.
2. Be prepared to drive 2+ hours to see a vet if needed (I do).
3. ANY vet that treats birds is better than none. CAV is ideal, but my current vet has gone to school for treating birds, studied it hard, and is not board certified. He is a great and capable vet all the same.
4. Don't try to treat the bird yourself, this often makes it worse. Don't give it random medicines. The only thing I recommend to "treat" seizures, is shining a heat lamp on the bird as they're waking up from the seizure. Not too hot, just make sure they stay warm.
