Welcome to the forums! 
When bringing home a new bird, quarantine rules should be applied in order to safeguard the health of your other budgie(s) and to avoid any possible illness the new bird may have to be passed on to the other birds in the house.
You can till quarantine your new budgie girl (for 30 days, more if she happens to be sick) by placing her on a different cage and room away from your male budgie.
It's normal for a recently acquired budgie to be scarred, not move around much eat very little for the first few days.
Usually new birds will eat spray millet, so you can try that to encourage her appetite.
Monitor her closely, see if her eyes are bright and alert. If she spends most of the days sleeping and is generally unresponsive, then it would be best to book an appointment at the avian vet for a proper check up, diagnosis and treatment plan if needed.
Since there is no real sense of urgency, I've moved your thread from the Emergency Room to Your Budgie's Health section of Talk Budgies.
