If you aren't willing to eat one have you considered trading the Amber Rock or, since you are probably pretty attached to her, the problem hen? Often a hen that is aggressive in one flock will not be so in another. People often want to "rehome" timid hens, and as long as you are honest about the problem with who ever you trade with it really might work out better for both hens.
BTW many chickens don't molt their first winter. If they hatched after mid July they more than likely will not molt till next season.
