I was convinced of the need to avoid store-bought when I cracked open the first of the last of the store-bought eggs, intending to cook it, to discover that the albumen (the white part) was a florescent green color.
I could not believe it at first. I thought I was surely seeing things. I popped open a second egg. This one was a normal clear color. I could compare the two and see the obvious difference in color. It was like someone had poured highlighter ink into the one egg.
I started frying, still thinking I had just completely lost my mind. Maybe the florescent part would go away if I blinked a whole lot?
Frying only made the difference more obvious, as the good egg turned a lovely white with a bright yellow center, while the odd egg's florescence fairly glowed.
All the eggs went in the trash. I don't know why that egg was green inside. But I think I'll take my chances with the backyard hens.
I tried to get a photo, but the color difference just doesn't show well on a camera phone.
