I am interested to see how large an egg they fit. My ducks laid 3 eggs the other morning, pretty soon they will be larger, right now they still fit in a regular carton. A guy at our farmer's market sells his for $9.00/dozen.
I don't know, as none of your duck egg's are here for me to see if they would fit. My NN that lay's the egg's that I had to get these eggs for is because her egg's are too long for the large sized carton's.
