I will be building my first chicken tractor and getting 10 hens. My tractor will be 16'X8' the coop part will be 6'x8' the coop will be 2 feet off the ground. I live in south Louisiana doesn't get very cold here. My question is do I need a solid floor with shavings that will need to be cleaned out or can I use hard ware cloth or something similar that would allow the droppings to fall through. I will be moving the tractor around the yard as needed to avoid build up.
