Can incubated ducks swim When you incubate a duck does it develop the oil glands necessary to stay float?

Yes, incubated ducks can swim. While it is true that oil glands are necessary for ducks to stay afloat and waterproof their feathers, these glands develop naturally in ducks as they grow, regardless of whether they are hatched naturally or incubated. During the incubation period, the developing embryo receives all the necessary nutrients and undergoes the appropriate physiological changes, including the development of oil glands, to ensure its survival and proper functioning after hatching.
