My four day old chicks peck, tear, and rip through the paper toweling on the bottom of their brooder so they can eat the wood flakes underneath. Only toweling was used the first two days, then I added the flakes under the paper toweling the last two days. I have two feeders for them (15 chicks) and they all eat out of them. Am I going to have to get rid of the wood chips and just use the toweling? Sooner or later, I am going go to have to go to the chips. Did I put them in too soon?
