I'm getting 10 day old chick's in may. Now I see some people who have brooder with shavings and some with puppy pads and some with paper towel. Now to start out for the first week or so which is best? Also if I use shavings how deep should I have it? I want to do this right and have clean up convenient. I'm starting in a 110 litre tote and then when they are bigger I should have a watermelon box from my grocery store to move them into. When they are in there I will be using shavings for sure.
