Beautiful. GCGot both. 2-wellies and 2-BC Marans. Egg color is similar but the Marans have a smooth shiny chocolate coat while the Welsummers are a textured dark matte coat with the occasional speckle.
The two in front of the basket are Marans and the one on top in the back is a Welsummer. We're getting incredible orange yolks out of them also.
