Local Eggs and Duck Eggs

I came across some sources for local eggs in the Bismarck Area.
First of all, of course, there are the eggs from the Berg farm sold at the Wilton Cenex Station. That's where I get mine. You can get free range, grass fed eggs here for three dollars a dozen. Duck eggs anyone? They sell local duck eggs here when they are available. Evidently ducks don't lay eggs reliably in the winter. Duck eggs are (evidently) prised by bakers. The whites in duck eggs have more protein and whip higher, making fluffier cakes. I found this post on cooking with duck eggs. I don't see duck eggs in my future, but if they're in yours, good luck.
