We have a variety of types and they molt a couple of times a year, thus giving no eggs. Eggs are richer, more protein, huge yolks. More nutrients in duck vs. Chicken eggs. Great for baking. If you use the instant pot to boil eggs, the duck eggs take the nine/ nine / nine as opposed to the 6/6/6 of the chicken eggs. Took me lots of wasted eggs to figure that one out LOL
