Strengthen feeding and management to prevent and control chicken pecking

First, remove the chickens that have a strong tendency to peck each other in time. Raise alone, isolate the pecked chickens, and apply bitter drugs such as gentian purple, berberine or chloramphenicol on the pecked parts, which can reduce inflammation and make the chickens know the bitterness. The maximum concentration of ammonia in the second 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 breeding density should be moderate, 20 chicks per square meter and 7 to 8 chickens per square meter. Usually to control the temperature, hot weather to cool down, the light can not be too strong, it is best to paint the lower part of the doors and windows and lights red, blue or green.
