Sun Conure with strange poop
My Sun Conure is 19years old and has within the last 3 days begun to have a very thin brown poop, accept for his very first morning poop which appears to be normal. He also has a horrible smelling gas. He always only pooped in one area of his cage, but he is now pooping where ever he happens to be.
He is still eating his fruit and nut, but does not seem to be drinking very much water. I believe he is sick, but we have no reliable vets in the area do you have any advice as I hate to loss him if there is something I can do.
