Can Coloured Eggs chage Colour?

[Stepnout]

As some of you know I am new to chickens this year. I have 5 barnyard mixed pullets, I think they’re great. They have given us many coloured eggs.
My first egg was brown, the second was green, the third was olive.
I assumed because of cold and shorter days my green egg layer stopped laying.
Is it possible the green egg layer didn’t stop but she started dying her eggs making them olive colour. The reason I ask I had 4 brown eggs and 3 brown eggs on 2 different days this past week. I am thinking the hen I thought was laying green eggs really didn’t and the green egg hen just started dying the eggs. Is that possible?
I also noticed a few days ago I had a hidden egg under the straw so I have been very diligent trying to sort this out. My wife had been collecting the eggs as I’ve been working ridiculous hours.
The picture on the right is from September and the one on the left is a few days ago I was sure I had 2 browns and 3 coloured eggs but not so sure as a coloured egg may have been under the straw. Today I got 3 browns and one coloured egg. I’ve been running my fingers through the straw to hopefully sort this out.
Your thoughts appreciated.
I’ve also noticed the eggs loose colour in the fridge. Has anyone else had their coloured eggs loose or change colour in the fridge?

White shells and blue shells will not change...
... but the brown coating on them can vary.
Changing color in fridge, maybe, the coating may oxidize a tad, or the moisture on egg can make it appear different-as can the 'color' of light(outdoors, indoors, different bulbs) that the egg is observed under.

I’m going to remove most of the straw to do away with buried eggs. I can’t imagine the hens laying multiple brown eggs in a single day.

Believe it or not these are all the same hen. I only have one green egg layer. Sometimes speckled sometimes not sometimes almost purple looking.

A brown egg layer won’t be laying blue eggs one day and white the next. The coloring can vary from egg to egg from the same chicken.
I have a rescue Frizzle Bantam hen who’s eggs range from a light brown color all the way to a shade off from Leghorn white.

I've seen my blues go lighter, my ight olive eggs go darker and vise versa, Wellsummer eggs are brown.. sometimes will lay solid color, then they will have speckles the next. Marans will be dark in the beginning, then go lighter with age.

Regardless of what the Industrial Health Food Complex may say, the brown color of eggs is not even skin deep. The hen who lays brown shelled eggs only spray paints her cackle fruits while they are still in the shell gland. As the natural chemicals in the hens body waxes and wanes her eggshells will darken and lighten in response.

Thanks everyone, I was thinking that green egg girl was dying her eggs different shades. I also notice the blue egg layer's eggs are light now.

Ok MYSTERY SOLVED! Thanks for all the help. I removed most of the straw as to remove the chances of hidden eggs. It is now obvious the bird I thought was laying green eggs was not laying at all. So the real green egg layer over time started dying her green eggs to produce the olive eggs. Today we have the olive, blue and the 3 brown eggs. Love the girls they are really doing a great job.
The black and golden EE with the cheeks laying blue. The white with grey spots laying Olive. The light Sussex, Australorp and the Brahma looking bird all layed the browns.
That olive egg is HUGE! The biggest egg to date

Very pretty eggs! Interesting that your white girl with spots is laying olive. Usually, that particular coloring of hen is a SBEL...super blue egg layer...and they are large eggs! Fun you got an olive color, happens. As you know.
