Thin duck?

[Quackersmom]

My Pekins are nice and plump. My buff isn't. It's the one who was having seizures. We got rid of the seizures completely and she was doing great but has within the last week or so started losing weight. You can feel her breast bone prominently. She appears healthy other than weight. She will chow down on peas and corn. As far as I know she is eating her food. Is it because they are still on grower? She is slightly older than the Pekins so I was gonna wait til they were old enough to graduate to the next food stage.

Any advice?

I would take a fecal sample to a vet's office and have them check for parasites.
