My 'hens' is acting like a Roo?

I post so many things/questions, & you guys are probably sick of me, but I have another question!

I have two hens, (well I think their hens?) that are about 8-9 weeks old (don't know exact age) . I was just in the backyard with them when one of my ''hens'' caught my eye. I thought (s)he was choking at first. She was stretching her neck toward the sky looking up, and opened her beak wide. Then I thought she was yawning? LOL, but then I came to a conclusion that the chicken might be trying to crow.. she did this about 6-7 times.

My other ''hen'' I believe is a comet, or a buff orpington (can't tell) (s)he always 'charges' at me, and it really freaks me out, (s)he runs at semi full speed and runs with her wings out, and her neck feathers puffed up as well. But I was wondering what the problem was and nearly climbed up a tree the first time she's done this to me..
Some people say that both of my 'hen's are actually roo's .
Any opinions? If this helps there are pictures of them;

I've asked similar questions before, so If you happen to run into my other questions.. sorry!

My think you have two little roosters.

You have two little pullets there. The motion you are referring to is when a piece of food does not go down comfortably - they are stretching the neck to try to get it to settle properly in the crop to be digested.

Edited to say: on closer look at the photos, the Speckled Sussex may be a roo. In the pic looking head on the comb does not look very big but when I looked at the profile view, it is much bigger than I first thought.
