Bird with swollen abdomen on bottom of cage by: Tracie
It is possible that your bird is egg bound, and if you do not get the bird to an avian vet it will likely die. It could be a tumor or an infection too.
Please use this Find an Avian Vet link to find a vet for your bird right away.
To prevent egg binding, see if you can find a high quality pellet like Harrison's or Roudybush pellets in your country. Feed your bird 80% pellets and only 20% heatlhy treats if you can find pellets there.
