Is it safe to turn my baby chick (2 weeks or so) on its back while holding her? She looks like she goes to sleep. But I don't wanna do it if it hurts her
Welcome to the flock! It's ok to put her on her back briefly for cleaning/grooming etc. but not too long. It's quite disorienting for them. If you are simply holding her, it would be better to keep her upright.
