Can I put chicks in with adults?

Hello, I have hatched my first quail chicks today. I have 2 king quail hens (the chicks mums), I hatched the eggs in an incubator as I was worried as one of the quail kept pecking the eggs. I replaced the hens eggs with clay look alikes and they seem to be (slightly) looking after them. Am I okay to put their babies in with them or should I just keep them indoors until they are older? If so, at what age should I introduce them? Thank you.
