I haven't been able to find Oxine locally to use as a sanitizer for my friends' coops. She is battling Infectious Coryza in her chickens and I'm trying to help. I have found something called Biodine. I think it is what vets use to wash their arms when treating livestock, etc. Description at http://www.domvet.com/biodine.html says: "Biodine is a 1.75% iodine complex indicated for use as a detergent , sanitizer, and disinfectant for poultry farms." Anyone have experience with Biodine and know if it will kill the bacteria that causes Coryza, CRD and related illnesses?
