We got our first 3 Scovie eggs this week! But they are disgusting! They should be white, but they are a mottled gray because of all the dirt and poo. So here are my questions: 1. How do you clean them off so you can cook with them? We tried sandpaper, but it doesn't work well when you have to sand the ENTIRE egg! 2. Do ducks eggs have the same bloom that chicken eggs have? Do I need to be worried about losing the bloom and if I do does that mean keeping the duck eggs in the fridge as soon as they are clean? 3. Do I need to be worried about washing them in water and the resulting osmosis like you do with chicken eggs? Thanks everybody! I really want to bake with the duck eggs but they are so gross I can't imagine cracking them into a bowl and not ending up with dirt and poo in my food!
