Ever since I got my budgie I haven't seen him eat his food. I have a seed mixture and several kinda of pellets, and nutriberries. His droppings are watery and green, it's not solid at all. The only time I have seen him eat is when I dropped a seed from my hamster's food and he ate it. But none of those seeds are in his food mixture. And also, I think he's losing weight. There's a line going down from his crop is all the way down his belly. Oh, and there's dried up droppings around his rump area. It was not like that when I got him.
