I just bought a 9 week old green cheek conure. I am handfeeding him formula. When his tummy fills up it is on his right side only, the size of a small marble. The salesman didn't tell me this at the time of purchase but when I went back to him he said he had noticed it but didn't think it would make a difference.
The bird seems very happy and healthy and eats well. Could you tell me if this is something that will affect the lifespan of the bird?
