We've had horrible wet weather and now have the gnat version of flystrike going on here. A sebright hen just died with pinpoints of blood all over her and the whole time I was handling her even indoors gnats just kept coming out of her feathers. I sprayed the rest of them down with dog mosquito spray and they seem to be doing fine. Hopefully I didn't just kill them all but they were badly suffering. Several abandoned the coop. All my young chickens were hiding underneath it and we only managed to collect about half. This happened a few weeks ago and it was solved when the door to the screened porch accidentally got left open. The porch filled with gnats that flew between the screens and plastic we put up over the winter getting trapped. I sprayed them all and killed millions that day. It seems the next round has matured and is after the chickens again. I'm going to try building a gnat trap with vinegar tomorrow and clean the coop. Hopefully by monday we can get a bug zapper. Those do work on gnats right? I don't know what else to do.
