Sexing Chickens

The guy I bought the cuckoos from said they were hatched in may and he also said they were pullets. I was just making sure. The blurry one is identical to the other

Barred rock males and females have feathers with both black and white stripes, and should not have any grey color. The males can look lighter in color than females if they get a double dose of the barring gene, leading to finer barring. That looks like a BR cockerel to me. A clearer picture of the other two birds would help.
