No, a duck is a bird just like a sparrow, seagull or a penguin. Mammals are animals that raise their young on milk. This milk is produced by the offspring's mother. A bird's way of giving their offspring nutrient rich food early on is through a yolk sac. A yolk sac is found in the bird's egg. Before hatching, a chick eats the yolk inside of its egg. This gives them the strength to complete their life's first big test, hatching.
