I'm 15 years old and starting to raise ducks (for pets; not slaughter) just for the heck of it, so I'm a newbie at this. Approximately 2.5 weeks ago, one of my largest and oldest ducks laid a total of 12 eggs. It's been sitting on the eggs ever since. What I am trying to acknowledge is when will the little ducklings start to hatch? Is there some part of fertilization that needs to be processed? I was wondering about this because I think it's been a long time for the ducklings to hatch, yet they haven't yet. I appreciate any given responses. Thanks.
