Fortunately the new run doesn't appear to have flood or pooling issues. But then -our back yard is not what I guess would be subdivision regulation? it wasn't obvious until I put the pavers down between the raised beds, but there's a slight incline, so that helps. I was thinking a light covering of rock just to help drainage. Not deep or complete bc I plan to put an herb garden in there for them once plants are big enough to be sustainable. Lovage, borage, mint. And their dustbath in there is a 7.5'x4' boxUs too! We had the droughtiest fall and spring and now we have rain, lightening, hail and tornados! And that’s how I found out that my new Guinea run floods badly. I had just driven a 1,167 mile trip and came home to a flooded run and panicked guineas trapped by the lake of gross water. I had to push it out with a snow shovel. Now I'm looking at today’s rain and worrying it’s flooded again but I'm on my way to work and can’t scoop water right now. I do have a plan to improve the drainage but may need to wait for the weekend.
