Hi. Mine get layers pellets and corn put in a large galvanized feeder which has a skirt, kind of like a rain hat. This shuts down at night to keep feed dry and vermin out. Also they get pasta and veg or porridge with fruit before roosting. This is served in ice cream containers but never has chance to get wet as it's all gone in about 2 minutes!! I've been putting straw in the run to try to absorb some of the wet and raking out and changing every few days as needed. This seems to work well, and they enjoy scratching among the straw for bugs!!
