I have heard the following: "brown eggs are different" "I/my kids won't eat brown eggs" "I only buy eggs from the store, I can't fathom the thought of eating fresh eggs" I have one co-worker who WILL NOT get eggs from me for that very reason! My hubby used to think brown eggs are different, he knows better now! The majority of my girls are brown egg layers on purpose! LOL
I only rinse my eggs with luke warm water because I think that "washing" them is not necessary, the large production egg facilities put the eggs through a "washer" and sanitizing solution before they package them, but then again when you have eggs coming from chickens crammed in a small square wire crate and can't even move around, then you have to remember there is the chance there is a dead chicken in there with them, rotting, that no one notices and the eggs roll over this carcass on the way to the chute for collection, "washing" and packaging, I guess they need to sanitize the eggs! I think that the chemicals or soaps they use seep into the eggs, no wonder people have so many health issues these days!
I tell people that store bought eggs come from places like that who don't care about the birds, they don't even notice if they die in the cage, but certain people just don't think much of it.
