The dropping should have 3 parts: Urine--should be clear liquid. Urates--white, toothpaste-like or chalky. Feces--should be well-formed tubes of varying colors depending on diet. If the feces is not formed into tubes, that is diarrhea, which may be normal if you are adding a watery fruit like apple or grape, but if it continues would indicate that a vet visit is in order. And yes, the smaller the bird, the more frequently it poops!
