in my chick brooder. I know it worked great for my snake's bedding. Don't know about for chicks in a brooder. To me it makes more sense than pine shavings ecologically since it's already recycled. It would be like re-recycling. A little goes a long way too. I also know it's sold by bird shops to put in the bottom of bird cages. Can anyone tell me their experience with using it for chicks?
