Anytime! You're welcome
There is an article here on BYC's about using eggshells as a calcium source. My chickens like eggshells better but my ducks really like the rock like oyster shell more.
I do feel like offering a free choice supplement calcium is extremely important for a laying duck.
I wish you the best. Feel free to share some pictures of your ducks. I, along with many others love seeing others flocks! Especially Runners!!!
