What breed of chick is this?

[Madsr24]

I know the pictures are not good to be able to tell, but if possible, can anyone tell me the breed of these chicks my sister got from TSC? Their yellow with black on their wings. She can't remember what they were.

Hard to tell as I can't see comb type or leg color. Possibly Deleware, or other Columbian colored breed.
