Update - Set 18 Muscovy duck eggs on 12-27-2015. Eggs were quite dirty, so I cleaned them with warm water and chlorhexadine. Wanted to try the method @Sally Sunshine posted, but was too lazy and just went ahead with what I hand on hand. Just candles them and have six clears, one blood ring and 11 that look viable.
12 / 18 x 100 = 66.67% fertile eggs
