Olive Egger Eggs blue and olive?

[Piopio2020]

So I have one olive Egger Hen who initially was laying olive colored eggs. This week she’s now laying bluish eggs. I have a very, delayed, slow to develop rooster BLR Wyandotte. He’s Relatively docile and finally this week we saw him trying g to mount some of the hens. My question, since the eggs changed colors is it possible to say the blue ones are fertilized? Thanks in advance. I think this is all fascinating!!!

Fertilized eggs don't change color. The same hen would not lay two completely different colored eggs either. One of your other chickens must be laying blue eggs.

Really? I only have 4 chickens, 1 rooster. The 2 Plymouth Rocks are the cream/whitish color, the olive Egger and the hen BLR Wyandotte who isn’t laying in the nesting boxes and her eggs are soft. She seems slow to develop like the BLR rooster...

Maybe she the BLR snuck in there and I didn’t see it? Thanks for your reaponse

Well, they become lighter blue in the absence of brown bloom. She is missing enough pigment in her diet to make darkly colored bloom.

Odd one out I’m sorry I don’t understand. So you’re saying she has a deficiency? They’re all just 21 weeks old

I don't know. It's possible, but I feel like the color difference is too drastic to be caused by the bloom.

Age doesn't cause it. But I'm not sure. Sometimes the first few are really dark, then they get lighter.
Any feed changes lately?

The OE started laying at 18 weeks before I started giving them layer feed. The first couple eggs from the OE were soft olive green. Other girls in my flock had soft eggs. So I introduced layer feed and oyster shells . Got hard eggs from OE that were olive. Now for the past 2 weeks, the eggs have gradually turned colors as you can see in the pic. The bluish ones are the same size as the earliest hard olive egg. I haven’t been able to eat it bc I think it’s such a pretty color.

The brown coating has thinned, so olive eggs are showing their blue shell color.
It's more about genetics than diet.
My OE's have very varied coatings.

In pic above, are her eggs the ones at 5:00 and 9:00?
