Put her in a small cage inside the aviary, you wouldnt want something to happen to her...
As far as the nature of her is concerned, let the flock establish a pecking order and it should be fine. Unless the breeder stated the reason for sale is due to behavioral traits, then you may want to move her own especially if you observe any bullying behavior. Usually the birds will work it out for themselves, as long as they have plenty of space in the aviary to get away from each other they should be fine to work it out on their own.
