There are several people on BYC who I know bring their chickens (grown) inside to watch TV with them or have movie night.
I have never tried it myself, but I can't see why baby chicks wouldn't appreciate TV.
I think anything you want.
Mine seem to also like the sound of power tools and can usually out-shout any music.
Probably not music festival level decibels but my guess is others in the house would complain before the chickens get upset.
Just watch how they are behaving and you will get a feel...
My chickens have always loved music. I think it may be because they associate it with treats because the construction guys play their radio and always share their lunch.
I think as long as you are letting them sleep at night it will be totally fine.
