This was taken a few months back; not recent.
Hello, about two days ago I noticed my five-year-old budgie showing signs of constipation (constantly puffed up, picking and scratching at his vent with his beak and foot, sometimes a small, dark and moist piece of feces will be clinging to the feathers there before he takes it off).
At first I thought it was because I removed the seeds from his diet and left him with only the pellets and a Vitamin A supplement given to me by his avian veterinarian. He got much better after I gave him back his usual mix of seeds and pellets without the supplement. I sprinkled some of the supplement on his food again today (as prescribed on the bottle), and realized that he became constipated again. Am I giving him too much? Should I not give him the supplement at all? Your answer would be extremely helpful, thanks!
