英文回答:
A duck's life cycle begins with an egg. The egg is incubated for about 28 days, and then the duckling hatches. The duckling is covered in soft, downy feathers and is able to swim and feed itself almost immediately. Ducklings grow rapidly and will reach their adult size in about 12 weeks. Adult ducks are typically between 18 and 24 inches long and weigh between 2 and 4 pounds. Ducks are social animals and live in flocks. They are omnivorous and will eat a variety of plants and animals. Ducks are important to the ecosystem because they help to control the population of insects and other small animals.
