I recently culled my flock of hens after a year of keeping a closed flock after I found out some of my birds died of Avian Leukosis. The state vet recommended using the "all out, all new in" approach to stop the cycle of passing this virus on. So, I am going to scrub down my coops with detergent and water while it's hot, summer weather, rinse them well and let them dry. Next step I will use Oxine AH. My question is do I have to use a fogger? I called the company that makes Oxine and asked if I could use a 1 gallon garden sprayer and they said it's ok. But, I read on BYC where someone posted a pressurized sprayer used has to have some adjustment to the nozzle end or the Oxine won't come out. Anyone have experience using a garden sprayer for Oxine?
