Accommodating hen while brooding

Wanted to get anybody's take on what steps to take to help my quail feathered d andver on brooding. For some reason today she decided to take one of my sex links eggs and start brooding it. It's a fertile egg that I'm sure of after watching my rooster go after the girls every day. She also lays her own eggs everyday and she too has a Roos too that gets her everyday. Waiting to see how this plays out, thnx.
