I inherited a sun conure who didn't have much stimulation about 7 years ago, he's approximately 26 years old. (A little back story - it was my brother's bird that he got as a baby but he got married and left him behind at my Mom's house where I visit him every day). I've come very far with him and he's become my buddy even though I can't touch him because he's a biter. He will only eat seeds even though I've tried every type of snack birds normally like. Recently Hartz discontinued the food he's been eating for years. I have some left and have been mixing it with a new one but I just noticed he has some poop stuck to his bottom. I do still see him poop, they're just not the same as they were. Does anyone know if it could be a result of this new food situation? He's acting normally in every other way. Thanks for any advice.
