Welcome to BYC! Try looking in the Duck section in the Learning Center- there are some great articles on raising ducks. Do you have any pictures of them? Ducklings are VERY MESSY but DEFINATELTY WORTH IT. To reduce the mess I would recommend getting a baking cooling rack/ or some hardware cloth and putting it over a baking tray, with the waterer on top- all the water they spill goes into the tray which can easily be emptied, instead of mucking up the bedding.
