Please refer to the Cobb Breeder Management Guide for general flock management
recommendations, as well as guidelines concerning post peak feeding.
Weights correspond to the weekly anniversary date.
Weights for weeks 2 through 20 are off-feed weights. From 21 weeks onward, (or when the
change is made to everyday feeding), birds can be weighed after a minimum of two hours
has passed from the time of complete cleanup of the day’s ration.
