I swear one of the eggs I collected today is purple. At least it has a purple look to it. When I first collected it I thought is was just the light but there is definatly a purple glow to it, i confirmed this by asking people what color they thought it was. The coop it came from is white leghorns, gold/ red sexlinks and a mystery black hen, she doesnt look like an ee she is big, she is also rooster picked badly. I just got them yesterday so these are the first eggs ive gotten from them. I will try to get a picture but so far no luck catching the color very well.
