Olive Egger starting eggs question

[LuciferRoo]

I have 4 Olive Eggers (Mars Bars) and they are at the age when they should be starting to lay.
Today, I found a small egg with blue splotches on it. Did this come from one of my Olive Eggers?
Obviously the egg is not olive. It is not even green (nor blue).
If it came from one of my young girls, is this normal? Will she eventually color the whole egg?
I don't mind if the eggs come out blue, but would like to have blue or green tinted eggs.

Would anyone with these type of chickens mind sharing their eggperience?

I have an Olive Egger that lays just like that and has since she started laying a year and a half ago. She came from Ideal Poultry. Where did you get your chicks?

Looks like the purplish bloom speckles I used to get from some light brahmas.

Does not look like a blue shell tho.
Open egg and immediately peel the inner membranes off to see shell color.

The very basics of egg color:
There are only white and blue shells.
Brown eggs have brown coating on white shells.
Green eggs have brown coating on blue shells.
The brown coating can be very light or very dark, and can vary day to day.
Then the bloom can add another aspect to the egg color.
Pink/purplish eggs are usually from the bloom on a brown egg.

I got mine from a local place here in Texas. It's not a commercial enterprise. From what I gather it's the wife's passion. They do however get chicks from commercial hatcheries so chances are that is where the parents came from.

I also have few Barred Rocks that just started laying and may lay in the same box.
