All ducks need to be fed Bird Feed daily, though an adult duck may be let out to graze. A healthy duck lays eggs every other day(2days); If they aren't fed then they will not lay any eggs, and they will only lay eggs if they are inside the Coop. The quality of the egg depends on the ducks affection towards you, and it's health. If you are incubating any egg, it will take 7 days to hatch. For a duckling to become an adult you will have to wait another 7 days. Ducks cannot be brushed, however they may be picked up, pet, or fed directly to raise their affection.
