Oh, that's interesting.......wasn't my camera, a friends 'smart' phone and she's not very tech savvy.
I'll have to ask her where she took the pic......
......I'm guessing in her coop late in the day (pretty dark in there) and it looks like it has flash.
It's very difficult to take accurate pics of colored eggs...even if it looks right on your monitor, it can look totally different on someone else's.
This is actually a green egg....taken with a smart phone and totally untouched.
