Maybe she has some damage to her reproductive system. But, does it really matter? Clearly it's not healthy for you or anyone else to live with this degree of aggressiveness. Very sad, but I would put her down as soon as possible.She’s growing spurs (like a rooster.) I know hens have spurs too btw. And trying to mount her sister, and making noises I don’t typically hear from hens, and flogging my feet.
