I am soooo angry! My 2 most favorite chickens ( we have 12) have died after we discovered they had mites and the man at the feed store recommended we treat with Permectrin. First we power washed the whole coop till it was sqeaky clean , we took the chickens out for a day and then sprayed it with the Permectrin solution as directed on the bottle. The next day we treated the chickens by spraying them under their feathers with a few squirts each ( it called for 1 ounce per chicken) . The next day they were STILL. Crawling with mites but 1 of my chickens seemed sick, could barely walk and died 48 hrs later! The next day another chicken same thing. And what angered me the most is the mites didnt die but the chickens did! WTH??!! Has this happened to any of you before? I thought this was safe and I know we mixed it right. This was our first time using this as we are new chicken owners as of Febuary this year...thought we were doing everything right as our chickens seemed very happy and healthy! Help anyone!
