I live in Florida & we've been receiving copious amounts of water. I am having a horrible problem with flies all over the feeders. My 3 chickens free range & sleep in dog crates at night, so no coop. The flies are covering the feeders & it's horrible. I've taken to sweeping up the spillage at lock-up time, but as soon as I set out the feeders & let the chickens out bam I have zillions of flies. I had the same issue a few weeks ago when we had a week of rain. I don't have this problem when the sun shines. I set out fly tape & that catches a lot. The girls don't want to eat & who can blame them. Any long term remedies?? Thanks!!
