Egg with odd blotchiness

[3KillerBs]

Is it from a new layer or a change in the egg that a hen has been laying for a while?

I have a EE who lays a similar egg. I have to many hens to be sure, but I don't think it started until she had been laying awhile. Never seen an issue inside and when candleing it doesn't look porus just a different pattern to the shell.

I think it came from my 1 year old who passed away suddenly on Easter. I'm pretty positive. She had about three eggs that looked like that.
