Every now and then she will make this :corwing" sound in the early morning, and i will get up "beat" her and give them some feed to quiet them down.
I'm really hoping you don't actually beat your hen?

The thing is, there is absolutely no reason for her to stop crowing, as you are rewarding her with food every time she does it! Every time you run out with treats you are encouraging that behaviour. So the first thing I would do is stop rewarding bad behaviour with food.
I really dont know what to do, we not allowed to have roosters in where i live. I am thinking maybe i should sell that araucana hen? Perhaps my black orpington will forget?
You still don't actually have a rooster. Just because she is crowing does not make her male. She is just exhibiting male characteristics. This is not unheard of, particularly in flocks where there is no rooster present. It also occurs when there are hormonal issues at play. I am presuming that your council still allows hens? If so, you just have a noisy hen. I'd try and bribe the neighbours with some fresh eggs and get them on your side. As long as you are all on good terms, and they don't make a noise complaint, you should be fine.
If you do go ahead and sell her, and she and the black orpington are close, then of course she will notice she is gone. The main thing is that she should have company of some kind, and you have other chickens so she should be ok. It will throw the flock dynamics into chaos for a while though, and someone else may well step into the araucana's shoes as head hen - noise and all!
