How old should quail be before

[ArtinNC]

How old should quail be before I start introducing them to things like lettuce or spinach? They are just a week old, but very active and flapping their little miniature wings as they run the length of the brooder. I'm a newbie at raising them, but I have to tell you, I have already fallen in love with them and want them happy and enjoying things other than just game starter.

Thanking you in advance for any information and your knowledge.

Mine are close to same age and mine love boiled eggs cut up. They go nuts for it

I give mine squishy stuff like grapes and banana. They love it.
