Our one hen has ascites and we went to drain her yesterday only to find she was covered in mites. Very odd because its so cold out. Either way I covered all my birds in DE and then we sprayed down the coop and run with spinosad. I didnt want to use it on the birds because its so cold out. I'm hoping just the spray down of the coop and run will be enough. If not I might have to get Permethrine dust. Any advice?
