When my previous duck hatch experiment failed, I reached out to the homesteading community to help troubleshoot my process. It was actually through those exchanges of pictures and stories that I was able to pinpoint my trouble areas. This community is as generous with their wisdom as any I have ever had the pleasure to be a part of! So much I have learned by asking and listening, they are an incredible resource, especially if you are missing "elders" in your circle. I encourage you to seek out a mentor or fellow homesteader to walk the path with you. It might save you a lot of time and grief, plus you'll have a shoulder to cry on, when the time comes. And believe me, the time will come.
The best thing about ducks is that even though they can be chicken-like, they are a whole other ballgame. Read here about ducks in the garden.
