Does anyone have any experience with controlling flies in their coop/coop area? The coop is very clean, but I have a hen with 2 open wounds and flies have discovered them. I am going to keep her in a wire cage in my laundry room for about a week, but I need to be sure that flies do not have access to the wounds after I return her to the coop (after she is healed). I was thinking about getting a fly zapper (electronic light). Does anyone use these or have experience (good or bad) with them? It's a good thing I love my chickens! I have spent over $300 in vet bills on this poor hen over the past month. First mites and lice, then one of her butt bones popped through the skin (we think from falling onto a concrete block after jumping), and now that absess has reopened and she has a second one. I feel like the worst chicken mommy ever!
