@LightMadeLiquid I assume you live in a somewhat warm climate? Your profile doesn't show a location.
I've always used plain pine shavings in the coop and the brooder area. The first couple of days I put paper towels down on newspaper when the kids are in a box in the house. After that they go to the brooder area in the coop with fresh shavings.
I get my girls in early June. I've found that works best for me as I tried late April/early May twice and all but one of those chicks started laying in the fall then quit for the winter. The June chicks have always laid through their first winter.
