Many factors interfere, such as:
These factors influence both productivity and the quality of fertile egg production. However, we know that good production practices appropriately implemented in the rearing phase are crucial for the maximum genetic expression of breeding hens, being a facilitator and inducer so that the birds can express the highest degree of health and animal welfare when interacting with the environment. The result of this is
