No, they look like partridge bantam Cochins or partridge bantam Brahmas.
Do not feel bad. My mother got me three "Silkies" from tractor supply, and it turned out that I got a Buff Laced Sebright, A White Rock, and a Silkie.
Those are birchen bantam cochin pullets. They are a very great breed of bird, I love them. I personally like them much more than silkies. Fantastic mothers, and super cold hardy (unlike silkies). I highly recommend googling images of what people tell you your chickens are and compare in the future.
