Hi, thanks for the nice intro and photo of Scarlet!
Introducing new birds is always a roll of the dice, it may be helpful to read up on isolation and integration before you decide to try it. This article is one place to start:

Best of luck to you and thanks for joining us!
If this was my situation, I would just allow the chicks to grow up and not add any adult birds. New birds have more issues to deal with. Scarlet should be OK as the chicks grow, eventually being able to hang out and do chicken stuff with her.
