I know I have read about this topic before. Are pine shavings okay for the brooder? Seems like there was a debate over pine or cedar. I should never have given my chicken books away. If I would have known I was going to loose my memory, I would have kept them. Or if I knew I was going to be brooding chicks.
Just be sure to use the large flake pine shavings. Sometimes they are able to eat the really small ones.
