Given your Coop a Thorough Cleaning Lately?
Disinfecting your coop is a crucial step which the small flock owner might normally overlook. Disinfectants should be applied only after the building and equipment have been thoroughly cleaned, ideally right after rinsing. Disinfectants can be applied by sprays, aerosols or fumigation.
Don’t be intimidated by the thought of “fumigating” your hen house: for most small flock facilities, using a garden type sprayer is the easiest method, and chances are you already have a suitable disinfectant around the house. The types of disinfectants generally used are phenolic compounds (e.g., Pine-sol, One Stroke, Osyl), iodine or iodophors, (e.g., Betadine and Weladol), chlorine compounds (e.g., Clorox, generic bleach), quaternary ammonium compound (e.g., Roccal D Plus) and oxidizing compounds (e.g., Virkon S, Oxy-Sept 333).
Follow the manufacturer’s directions for mixing and dilution of these disinfectants. A good rule of thumb is to apply at the rate of one gallon of diluted disinfectant per 150-200 square feet of surface area. For a more thorough disinfecting, soak waterers and feeders in a 200 ppm chlorine solution (1 tablespoon chlorine bleach per gallon of boiling water).
