That’s way too much work for me. I just limit my egg sales starting in August and store unwashed eggs in the basement refrigerator. My girls usually are still laying through mid October and start laying again in mid January. So the eggs I store in the refrigerator is enough to get me through the winter. I haven’t bought eggs since my first chickens started laying in early September 2018.Have you thought about waterglassing as a way to preserve eggs? I plan to start doing that when we can't keep up with eating them. They can be preserved for a year to 18 months. I'll need them next winter.
