Only the bird in picture #1 is a pullet-- the other 6 are all cockerels. Compare her comb to the others. It's smaller and shows far less color. Also compare her plumage to that of the others. Her feathers on the body are all similar while the males have all sorts of different colors popping out. Her breast is similar in color to the rest of the body while the males are growing black feathers in their breasts. A female of this color patter would never have that. Soon the males will develop more of the longer, narrower hackle feathers and they will get them in the saddle area, as well as developing sickle feathers in the tail. By then I think you would know the difference. And don't feel at all bad-- we have all learned over time with experience and you will too.
