I inherited a chicken coop when we moved into our place. It's made of metal sheeting and wooden beams. The floor is dirt, not hard but soft, and I've been using a combination of wood shavings and straw as bedding. Problem is that around the edges of the coop it's damp and the wood is starting to rot. I put down some wooden planks but they're only absorbing the moisture. Ive taken up the planks and returned to the dirt floor. I'll have replace the coop eventually but in the meantime do I stick with the dirt floor, wood shavings and straw? Anything I can do to reduce the dampness in the corner and along the sides? I'd be most grateful for any advice.
