I don't know who laid it. I have an assorted mix of brown and white egg layers. BR. RSL. PR. WR. RIR. WJG. Dom. Cochin. SS. BA. From the egg color I would make a guess and say it's one of the Rhode Island reds or the partridge rock or one of the red sex links. They are the ones that lay their eggs in a box on my porch. Lol.
