We converted an old barn style shed into our coop. The front and back have framing with hardware cloth. We removed the walls and replaced the door with a screen door because it gets very hot in florida without air flow. The problem is that when we get a heavy rain or storm the water blows in and gets the pine bedding soaked, because it is a concrete floor this moisture has nowhere to go so I am forced to clean out the coop and start all over. My question: Is there a better bedding choice for our situation? The coop is 10ft by 10 ft and there are currently 20 chickens and 3 ducks. 10 of the chicken will be processed in a month. Any advice??
