My eggs are usually clean when they come out of the coop. All I do is rinse them in cold water from the tap. No rubbing. Then I put them in the frig. If an egg is overly poop-covered, I just return it to the chickens.
I'm BJ and I just adopted my neighbor's 5 laying hens. I thought I'd come here and hopefully learn something! I believe I have 2 Rhode Island Reds, 2 Buff Orphingtons, and 1 Lacewing Wyandotte.
