I made this big brooder with boxes and dumped pine shavings in the more I messed with it the more I didn't like it I noticed fine saw dust like particles covering my hand like powder even though it has majority big flakes..Not sure this is good for first week chicks or any at all for that matter.I haven't put them in it yet I'm scared they will eat it too! They are doing great on puppy pads and paper towels eating and drinking but I need some opinions on what to do!!!??
