My son built a pretty little "farmhouse" coop with a ramp down to a fenced in run. The house is too small (we're talking 6 birds) for any feeding to be done, and the outside run does not have roof. I put together a PVC feeder, with a cap on top, but after a few weeks its got lots of mold in it. We'd really like to keep the food off the ground, and the PVC feeder seemed like a good idea, but the mold situation (presumably because it's getting too much moisture in it, is a problem. Any other suggestions for a feeder setup that we might try in the outdoor run (short of bringing them fresh feed every day)? Thanks.
