The average birthday age of Muscovy Duck is 172.88 days, and the laying age is 153 days.

Muscovy ducks are in full bloom in spring, and the egg production rate begins to decline in the middle and late September. When the laying rate is about 30%, the muscovy duck can be forced to molt manually, and the muscovy duck will start laying eggs again around 1 month. It takes 120 days for female ducks to lay eggs.

As the saying goes, ducks lay eggs, first remove oil, then gain weight, and finally scrape hard. Ducks are thin in summer because they have been laying eggs for several months. If they continue to lay eggs at this time, their strength will be greatly weakened, which will seriously affect their spawning in autumn.

Therefore, when summer comes, it is necessary to lock up all the ducks that lay eggs, pull out a few big hairs on their wings and tails, and feed them only with water for three days in a row, forcing them to pick out all their eggs.
