dust bathing in the grit

[spgj1]

I have a small dish full of grit which they devour, but I have one the 2 week olds trying to dust bathe in it. Is this normal? and is there something i should be doing different in the brooder for them?

Cut a small box down (2-3 inch lip all the way around) and give them some dirt to scratch and play in. Keeps them from picking at each other and toe picking. 24 pack soda case bottoms are perfect.
