Local chicken breeding should choose a suitable site to do a good job of disinfection.

Native chicken breeding should choose places with leeward to the sun, flat terrain, high dryness, convenient access to water, far from the village, convenient transportation, small canopy and sparse fruit trees.

For the new site, after ground cleaning and washing, the site is sprayed to disinfect the brooding production area with 10 to 20% lime water or 1: 1200 times disinfectant, 1: 2% caustic soda, etc. On the basis of the above methods, the brooding room was fumigated with 14g potassium permanganate plus 28ml / m3 formaldehyde for 1 to 2 days (drinking fountains, buckets and other utensils were put together for disinfection), and ventilation was opened for 1 to 2 days.
