The breeds of chickens are divided into three categories according to production performance: one is the egg type, the second is the meat type, and the third is the egg meat type. Among them, egg-type chickens have the highest egg production rate, followed by egg-meat combined chickens, and meat-type chickens have the lowest egg production rate. Under normal circumstances, the meat type chicken is out of the bar for 40-120 days, and there is basically no chance to lay eggs.
