Baby chicks are 1 week old, when can I feed them bugs?

[Chickmema]

I was just wondering when it is ok to feed baby chicks (1 week old) some worms and maybe some fruit and things. I have baby grit for them but don't want to give them something they shouldn't have. I see some people give yogurt and they love it, I was wondering what kind of yogurt can I get them I assume just plain but want to be sure.
Any advice would be helpful.
Thank you very much!!

My son and one of his friends spent an evening last summer picking small moths off the window screens and throwing them into the brooder for the chicklets. Both the kids and the chicks had a great time.
