Who are laying these?

[Flip-N-Flogging]

I am curious about a certain egg color I get. I have some easter eggers that I can always account the green and blue eggs, I can always identify the chocolate eggs from my marans, I can always pick out my RIR because she seems to lay them right as I collect everyday. But those are the only ones I for sure know what color they lay. The ladies I have left are SLW, Black Sexlink, and Barred rock. I sometimes think I can tell them apart, but I always get this mystery egg which is a creamy brown with a ton of speckles on it. I guess this could be a fluke from any of them, but out of those breeds is this a normal egg color to one in a particular? I'm not hatching any, just curious for my own education.

My Barred Rocks only lay a light to medium brown egg. There is a chart that shows info about breeds and what color eggs they lay. I have found it helpful.
