Not the greatest pic (don't mind the heat lamp, it is not on). The cockerel is right behind the barred rock and then the two pullets are just to his right. None of them are colored right but I think yours are pullets as well.
They look like pullets. I ordered a trio from Murray McMurray that are about the age of yours. The pullets look just like yours - poor quality coloring. The cockerel is almost all black.
