I have a terrible drainage problem !!!! Water flows right in front of my coop and out the gate area and settles in the yard under a tree, we have our septic above ground so there is a big mound so the water drains off it too. all of this selltles in the same area alomst. I am thinking if I put a rain garden there it will help channel all extra water to it? I have seen on all the dumb DIY shows about them but no one ever has to deal with chickens and now I have goats. How could I design it to hold water when needed but keep the rocks in place? I guess I can always enter a DIY contest about yard problems. If I won I would totally wear a BYC T-shirt.!!!!
