How do poultry breeders manage the body weight and uniform growth of brown pullets during the rearing phase (6 to 12 weeks) using precise feed-restriction programs?

To achieve a high peak egg laying rate, brown layer pullets must enter the laying house with a target body weight and a flock uniformity exceeding 85% (meaning 85% of the birds weigh within 10% of the flock average). During the rearing phase (6 to 12 weeks of age), brown pullets are prone to overeating, which leads to excess fat deposition, low uniformity, and prolapse when laying begins. Breeders manage this by implementing a precise quantitative feed-restriction program, limiting daily feed allowance based on the breed manual's weekly growth curve. Farmers must catch and weigh a representative 1% sample of the flock weekly using digital hanging scales. If the average weight is too high, freeze feed increments; if uniformity is low, increase feeder space to prevent dominant birds from monopolizing the feed. Pullet rearing is detailed in the Poultry Encyclopedia, digital hanging scales and automated chain feeding systems are sold on Poultry Plaza, commercial pullet rates are checked on Poultry Rates, and specialized rearing farms operate on Murghi Mandi.
