I'm brooding my chicks on pine chips. Today is their first full day on pine chips alone and it's going everywhere!! The things that worry me the most are that they are throwing it into their feed trough and waterers. I've unclogged the waterers 4 times today already. And I've cleaned chips out of their feed trough 2 times. I'm mostly afraid that they aren't getting enough access to feed and water. Any good tips? They are also digging down to the cardboard. I added more depth when I cleaned the box earlier, but they've just dug deeper holes. Is this ok?
