Maybe I have a better sense of smell than you. I eat 7 oysters a week for zinc, which is good for the sense of smell.I have eaten true free range chicken eggs from my property for 20+ years as seen in my post and never had this odor or whatever you are talking about.
Some FR eggs have a disgusting odor raw, I've also got the from store bought FR eggs.
Many FR egg farmers wouldn't think of eating one of their eggs raw because they're aware of the odor that tends to make you want to "toss your cookies."
