I was going to do a treatment today but there was thundering and lightening all around us and dark, but we didn't get a drop of rain. I sprayed originally for flies but I think some of the birds mostly in one coop may have had mites. I saw some minor feather loss so started my spraying regime. I have already sprayed the past couple of weeks. THe birds are looking better. I suspect mites were attacking them at night because I didn't see any when I checked during the day. We have been getting evening rains so I haven't went out at night to check the birds and since they are looking better I don't think I need to. Will do a spray tomorrow earlier. Off to collect the eggs.
