we are having the same problem with our eggs! My daughter was making eggs, and she handed me my plate. I took my first bite and vomited because my Eggs tasted the same way chicken poop smells! I thought maybe she hadn't washed them very good, but it happened again the next 2 times I tried to make eggs. I cleaned them very well, with dish soap and scrubbed them very good with a brush. Then while I was cooking them, it smelled like chicken poop!
While I don't know the answer to this and am trying to figure it out myself, maybe we can share knowledge and experiences and figure it out together. The only thing I can figure is that it is because the chickens are pooping on their own eggs, and eggs are porous. But I also know that there is an outer layer that Coates the eggs before you wash them, but once you wash them, then that's when you have to refrigerate them because bacteria can get into the pores. So I think the outer layer is getting damaged somehow before washing, and it's allowing the bacteria from the chicken poop into the pores. Our chickens do have mites right now, and my boyfriend said he even found a few holes in some of the egg shells from the mites. So my best guess is that the mites are destroying the outer protective layer of the eggs. Can you check and see if your chickens have mites as well?
