I have a 4x8 chicken tractor attached to a 14x14 run. The floor of the tractor has wire (2x4 inch holes)on it (for predators) and the poop builds up right under the roosts since the tractor does not get moved. I have to unattach the coop to move it back and then dig up all the poop and soiled mess. Then I put dried horse manure from the barn as a new dirt floor. Is there a better way? I would like to be able to clean it out without having to move the whole thing back. Could I put straw ontop of the wire so that hte poop was caught on that instead of catching on the wire? Then could I rake the straw out every so often?
