I have my eleven chicks in a 55 gal reptile tank and clean it daily. I have newspaper down , then a layer of paper towel and then the pine shavings. I can easily roll up the newspaper and remove the mess. All the chicks run to one side, as I don't even take them out of the brooder to clean. When I have the newspaper rollled up at the half way point the chicks happily stay at one end while I take a hot rag and clean the glass tank on the other side and then lay down more paper. Then I coax the chicks to the clean side while continuing to roll up the mess and throw away in the big garbage bag beside me.
my chicks are 3 weeks old and definitely need a fresh cleaning daily. They poop ALOT. I made a stupid mistake of letting them on the floor , in the basement , while I did a real thorough cleaning. I put a large old towel down on the floor hoping they'd stay on it and poop, well they pooped on it and every where else. Wow they poop alot. So not such a good idea to let them free range on your floor for any length of time - argh.
