Integration is a lot harder than throwing a bird into a flock and hoping they'll all play nice.
Your coop setup should, ideally, having two separate housing areas and runs for integration. I raised two different hatchery clutches in two separate runs where they could grow up seeing each other and communicating through the wire and they integrated seamlessly and without so much as a squabble.
If I were you, I would either wait until she is fully grown before attempting to house her in a nextdoor run for a few months, or opt for introducing more than a lone bird as others have suggested.
