Soft billed birds like Finches and Canaries swallow their seeds whole. Parrots are able to remove the hulls from the seeds with their beaks. Now that we know about the gizzard, we should note that the soft billed birds could use a little help grinding down these whole seeds. This is why we introduce small amounts of grit they can swallow which will help grind up the seeds while in the gizzard.
I do hope we made some headway in clarifying the options you have to feed your bird. Feel free to contact us with specific nutrition questions.
