I have many many layers of newsprint on the floor of my brooder, covered by a layer of pine chips. When it's time to clean, i remove all the stumps and feeders and things and i clean them all up and set them aside. Starting at one end, i take the top couple of pieces of paper and i start rolling. The dirty shavings get rolled up in the paper. I roll a little and i gently pull it all toward me and i roll a little more. The chicks are at the opposite end from me. They wind up on a clean sheet of newsprint because everything else has been pulled out from under them. Then i put all the cleaned items and fresh bedding back in. I read this somewhere, tried it, and i love it!
