Ducks are three months old; McMurry Hatchery tells me the male tails curl up at four months and the females will lay eggs at six months. A friend tells me they love to hide their eggs. Not sure what sex we have yet, Baby Huey is a giant Pekin Duck. Remember the small wadding pool is actually about 4 inches high. They love mud and water and will create 'holes' with their beak where the soil is wet. Reminds me of hogs.
