Very Cute! Unfortunately neither one is a Cream Legbar.
If they did indeed come from a CL hens egg, they were fertilized by a different breed rooster. They are likely sexlink, the one with the head spot being male (don't confuse this for the CL auto sexing trait being passed on). Do you know what type of comb the chicks are displaying? Have you contacted the seller to ask the other possibilities?
X2 so sorry! But they are cute chicks
