The average daily egg production per chicken is a key indicator to check the level of chicken feeding. Under the premise of high egg production rate, increasing egg weight is one of the effective measures to increase the daily egg production. Body weight and egg production rate were negatively correlated and positively correlated with egg weight when chickens raised in chicken layer cages for sale. The greatest impact on early egg weight is the weight of the laying hens when they are transferred to the laying hen house.
The weight at 18 weeks of age has a decisive influence on the weight of the first egg. Therefore, professional households must pay attention to the early feeding management of laying hens in chicken farming equipment, so that the weight of the hens at the time of production can reach the standard weight, or the upper limit of the recommended weight range.
