We've finally had some rain here and it blew sideways. Their feeder got wet and I cleaned it out and put in fresh feed. But they were really messy eaters and there was chicken feed on the ground. I now have flies. It smells sour out there. I took a shovel and turned the soil. Will that do the trick do you think? Or do I need to get some DE? Their feeder is in the run, but the run is covered. I have since hung their feeder a little higher so hopefully they won't be quite as messy. Any suggestions are much appreciated.
