Because the breeding ability of breeder is very strong, they growth fast and weight gain fast. Then if you do not control their weight, the breeder's weight can easily exceed the standard, thus affecting the production. Therefore, when breeder chicken aged in 4 weeks to 24 weeks, always be limited feeding.
Restricted feeding can first ensure that the breeder's body weight meets this breed's standard. If breeders overweight, especially hens overweight, will have significantly reduced egg production and a lower rate of qualified eggs. And overweight often causes leg problems, too.
