go to your farm supply store and get some (horse bedding) wood chip pellets or stall dry and pour in that area, it will soak everything up. and add to the flooring of the pen. The STRAW will retain every bit of water and not allow anything to ever dry up. wood chips would be better for not retaining the water. they would soak it up but would dry out in the sun. Straw will not dry out ever.
