How to prevent and control chicken feather-pecking vice? Strengthening feeding management is key

First, promptly remove the chickens with a strong tendency to peck each other. Raise them separately, isolate the pecked chickens, and apply gentian violet, berberine, or chloramphenicol and other strongly bitter drugs to the pecked areas; this can both reduce inflammation and make the chickens retreat after tasting the bitterness. Second, the ammonia concentration in the chicken house should not exceed 20 ml per liter, carbon dioxide should not exceed 0.15%, and hydrogen sulfide should not exceed 10 ml per liter. The stocking density should be moderate: 20 chicks per sq m, and 7 to 8 growing chickens per sq m. Usually, the house temperature should be well controlled; when the weather is hot, cool it down. The light must not be too strong; it is best to paint the lower parts of doors and windows and the lights red, blue, or green.
