have had my budgie a few months now he is very happy. when he flies around his feathers on one side break off.
The regrow but the same thing happens again. He does'nt manage to control where he is heading for. is there anything i can give him. Do i take him to the vet? His name is Hari.
thank you

It certainly sounds like you may need a vet to give a proper diagnosis, but a few photos of him from the back showing his wing feathers may be helpful.
