Strange looking egg

[NatureHouse17]

Hello!
First of all, sorry if I didn't put the topic in the right section.
This time I have doubts related to some egg yolks that in my opinion look strange.
The yolk has more white membrane, which I thought is the chalaza and the albumen is kind of blurry. Also, as you can see in the photos below, the yolk separated from the albumen, which I know it as a bad sign. This is the second egg like this in 2 weeks and is fresh, just 4 days old. In the second photo,the signs are more clear.
I'm a bit concerned, mostly because I sell eggs in the area (a small, neighbourhood "bussiness") and, even this have never happened before and everybody saw that they are high quality, right now I'm afraid they may find such ones which wouldn't be fine at all.
The eggs are from a some 5 years old Isa Brown.
Any ideas if that egg is ok? Thank you.

there is nothing wrong with the egg color. if your chickens free range or forage a lot, then she should lay dark eggs. a yellow egg yolk shows a good, balanced. the orange egg doesn't have as much nutritional value. the lack of a shell is a sign of early laying, or your hen is being roughhoused.

Are you sure that egg looks normal?
Even with that blurry albumen and the dense membrane?
They are free range, yes. The shell of the egg was totally normal, just the inside put me on thoughts.

The excess membrane and cloudy whites do look a bit odd.
Is this happening with regularity or just this once?
Just one bird or multiples?
Hopefully you can tell which bird by shell color(not always possible, I know).

It's the second egg like this in the last 2 weeks. It never happened before those.
I don't know it for sure but I think there is a certain chicken that lays them.
