If your sand is coarse and very heavy, you can add dry soil to it or peat moss or simply use dry soil as the dirt bath medium or plain peat moss. Peat moss makes an excellent dirt bath for baby chicks since it's light and fluffy and they can really toss it around with total abandon.
It will increase the amount of dust that becomes airborn, and if the chicks are in your house, you might want to hold off until you can move them outside.
Dirt and/or a chunk of sod from near the chicken yard is what I use at about one week in the brooder.Just sand?

How long have they been in the coop?
They are about 3 weeks old IIRC...let them go outside into their run.
Dig up a chunk of sod to help them get a hole started.
