I have a year old Saxony duck that is taking a lot longer to finish molting than her sisters. She is still looking really scruffy and the rest of them are pretty well all set with new feathers. Is this just within a normal range of time, or could there be another problem I should attend to. She eats well - maybe a little on the chubby side compared to some, but about average overall. thanks for any insight or experience you can share.
