Hens breeding hens/Masculine chickens

[TheTwoRoos]

So I need soem help understanding this.I have a year old polish HEN,100% girl,who is most defiantly all FEMALE.Lays eggs,has female feathering so and so fourth.I have these two brown favorolles in my flock who are older then the rest (not sure picked them up way alst year when my birds were younger)and they seem to be the outcast of my flock.I do have a rooster.I notice what often times my hens will do,is lietarlly attack the brown hens while the rooster is breeding them, certain ones do this,however the polish bird lietarlly fluffs up just like a little rooster and when the rooster gets done breeding the bird, legit hops on the back of the bird and starts breeding it,like literally trying to touch clocas with it.It then hops off and puffs up and around the bird, so odd witnessing this behavior escpecially with a rooster in the flock present and defiantly dominant,it even has the rooster confused trying to figure out what is going on ,Any ideas?
