If you find a duck egg in the wild or one that looks abandoned in a random corner of your homestead, chances are, it’s infertile. If you find a whole clutch of eggs that are still warm, however, there’s a good chance they contain baby ducks. Leaving them in place gives them a good chance of survival. But, if you want to make sure, you could use one of the three methods described above to evaluate their validity. If you are confident they’re viable and are desperate for cute, fluffy baby ducklings, then pop them in an incubator and hatch them!
