So i got a peach-faced lovebird that's a little over 6 months now and every since he came to us he's been acting a bit strange. He's been getting really frustrated and when he does he starts choking and needs help to puke his food out which also never helps cause he just keeps flapping his wings, running around and choking. We thought that maybe the sunflower seeds were too big for him and he might be choking on those so we stopped giving them to him but it didn't stop. This month we thought that maybe it was getting better but these past days it only got worse and worse so we finally took him to vet. She listened to how he was breathing and said he was fine. I know he's not so we showed her one of the videos where he obviously was choking and getting frustrated over it and all she said was "Oh he's just playing". I don't know what else to do. I know I'm not overreacting and vet was my last option. It will only keep happening but apparently he's "fine". Anyone knows what could be wrong with him and any tips on what to do now?
