i have 5 hens. The best layer is the dominant one and crows every morning to assert her dominance.
To try and stop her crowing I am introducing a new hen from a breeder who has picked his most dominant girl.
My question is: (after the quarantine period) do I put the dominant girl and new girl together & let them fight it out & hope new girl wins... OR Do I put dominant girl in isolation and introduce new girl to the flock & hope she becomes the alpha, then reintroduce the dominant girl and see what happens?
Welcome to BYC!
How do you plan on 'quarantining'?
Pretty hard to do in a backyard flock, see links below.
I'm afraid your theory may be seriously flawed.
Either way you could end up with some bloody birds,
not to mention the stress it will cause for all involved.
Not all dominant hens crow, most don't - even without a cock in residence.
Tho your crower could get her butt kicked and stop crowing
Is the crowing a problem because you are not allowed to have roosters where you live?.
The 'single bird' link Ken posted is excellent.
Here's some more integration tips and links.
Consider biological/medical quarantine:

Integration Basics:
It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.
Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.
In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.
The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.
Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.
Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can
really help. Lots of diversion and places to 'hide' instead of bare wide open run.
This used to be a better search, new format has reduced it's efficacy, but still:

This is good place to start reading, BUT some info is outdated IMO:
