After the fresh rain we had the other night catchment attached to the chicken coop is about half full. Its made out of a simple bent piece of metal we found in the forest and hung up with a few bent nails at the corner. The roof is not very large and I was amazed when I went to fill their water this morning. Its nice not to walk back to the house to full up the water anymore. And its one less water resource needed on our farmstead.
