From green to blue?

I have 12 chickens but only two laying...a brown leghorn and 1 easter egger. Out of the 12 I own 3 easter egger the 1 that's laying and 2 that are 25 weeks old. My easter egger that is laying only started about 3 weeks ago and she has always laid an olive looking light green egg. The other day I thought both hens took a break and then I got a teal light blue egg. Is it possible another chicken started laying or could her egg color have changed? The blue egg was not in her normal laying spot but if it wasn't her then she hasn't laid in a few days. Today she keeps running in and out of the coop and I had my kids check and there was another blue egg and then a white one from my Brown leghorn. Another chicken could have gone in there without me seeing, but the only chickens I have seen in there at all today are my two original laying hens, but they both lay in the same spot every time. How do you guys keep up with whose laying what? I've read different stories. Yes they can change color because the brown coating goes on in the last minutes before they lay and the amount can very which determines how green and blue they are and then I've read they can't change colors. So confusing. Personally I don't care what color they lay Im just curious if I should be celebrating another one of my girls starting to laying or not.

I have no experience with EE's, but do see my brown egg layers' eggs change in depth of color, but never that quickly. I would bet you have another one laying.

I have an olive egger / Easter egger cross and she lays green eggs witch when warm look blue like baby blue. This is an example of an egg of hers that was in the fridge an green and I held half of it and as it warmed it starte turning blue. This isn't photoshoped. If you pm me your email I'll send you a video of her laying an egg that's bright blue and then turns green as it cools. It is freaking awesome!!!

I think the color chane has to do with the chicke carrying both genes, green and blue egg. The blue egg gene is actialy the shells color and the green gene is like a paint that gets applied after the shell is formed in the body. So it's like a blue egg with green "paint" on it. I know the warmer an egg is the more seceptible to bacteria and the more open the pores so it may be showing the blue more and when it's cold and the pores are tight together the green may show over it. Not really sure but it's cool as ****

The green eggs that normally come do get darker when they warm up but have never even had a slight blue tint to them. They are very olivey...is that even a word? Lol These new ones are very much a Robins blue. I wish it would let me upload pictures!

Here we go...
Here are her normal eggs



Here is the new one...



They are brighter in person. May phone just isn't doing them justice.

Well there about the same size and shape. Pm me your email and I'll send you the coolest video of the egg changing colors after being layed

Actualy after watching the video I have a new theory. When it's wet it's green and when it's dry and warm it's blue because in the video it comes out brown ish green and wet and as it dries it turns chalky blue. I know when eggs are cold they are wet cause of the condensation and the bloom protection

The color of the eggs also changes based on the background behind it

So these two eggs layed by the same hen. I know this cause I have no other hens who lay anythig other than brown and off white eggs. The green one is cold and has a condensation on it from being cold and the blue is warm fresh laid and dry. If you zoom in close to the green you can actualy see it looks like it's textured little circles of color. It's awesome lol. You can see on the side of the green how it's starting to dry and warm because it's next to tw warm and and starting to change color
