Those are blue, and beautiful ones at that! Splash has more white/grey mixed in. They both look like pullets to me...you are lucky, out of the 6 that I ordered only one had that pretty of blue coloring. The rest were light grey and splash.
Blue.I just bought some splash chicks from a breeder that feathered in blue as well but they also didn't look like a splash when I bought them as a few days old
