60 freedom rangers arriving tomorrow. Have raised several chicks before but not that many at once. Have an 4x8 brooder. Here is my question, Can I place a wool army blanket on top of the wood chips for the first several days. I know that slick surfces are a no no. Blanket seems rough enough to me. Used paper towels before but brooder wasn't this big. Paper towels seem like a waste and time consuming.
