Cockatiel huge bulge under base of tail
One of my cockatiels has a huge bulge under the base of his tail. This budge has been there for months and does not affect his eating. He is such a good little bird. I have no means of transportation to get him to the vet - so I watch my little bird continute to pull himself up to the higher perch.I started cleaned it and it looks like a form of diaper rash when the feces melts off so I put a coating of neosporin on his bottom. Any suggestions? Is this a tumor or a hernia? Any advise you can share would be appreciated.
