In the past i have used a tractor coop to raise broilers. It has worked well but I find that I have to move it almost daily to keep the ground from becoming to soiled. I usually raise 20-25 at a time in a 10x10 tractor. My tractor coop is too heavy and this becomes a pain. I have plans to build a much lighter coop but don't have the time right now. My question is that I have a 12x12 stall in a barn that is not being used. If I fill it with pine shavings to about 4 inches deep how often would I have to replace it or add to it? The initial cost in shavings would not be too bad but if I have to replace it too often it would quickly become too expensive to justify. I plan on putting about 30-35 broilers in this stall. If anyone has any experience raising broilers on litter I would love to hear any advice or opinions. Thanks in advance.
