Flies and mosquitoes are driving me crazy around our coops and runs so I KNOW its driving our chickens crazy too. We spray malathion in our garage and around our doors to help keep down on mosquitoes and it seems to help. Would it be safe to spray around the coops and runs with it also?? If so, when would it be safe to let the chickens out for a field trip again?? The youngest of our girls is 22 wks old.
