My friend bought these birds at Tractor Supply. They are black white white on top of their heads. Any ideas of what breed they are??

Coming from TSC, unless they were marked Barred Rock, I would guess they are their Commercial Black. Are they out of the Pullet Bin? There are a couple of threads here on the boards about the TSC Commercial Blacks.
