Nope, females shouldn't have streamers. Are these all the same bird? The first one looks like a dark partridge pullet. But, that last picture very clearly shows streamers (and is a great picture of them). Streamers= boy.
All the same bird. She/he is so girlie in every way except the streamers. It has short, round feathers on the neck, didn't start growing a comb till about 6 months...this is a hatchery bird too. Haha, this one is tricky. Glad to see that one other person has a hen with streamers. I'll let you guys know when I find out.
