>—Lancaster Farming, Saturday, November 21,1981 t - "Quality Pullets Determine Your Destiny 810-4 The best way to know whether the pullets are meeting the body weight goals recommended by the breeder is to weigh a sample of birds at regular intervals The first weights should be recorded a week before changing from the starter to the grower ration. This weighing would be at 4 weeks of age. Re-weigh at least every 2 weeks there-after, but not at intervals of more than 4 weeks. A sample of 50 to 100 birds should be weighed in each house. A 100-bird sample makes calculation of the percentage of birds above or below the desired body weight range easier and increases accuracy In a floor house, the sample could consist of five groups of 20 chicks. In a cage house, the 100-bird sample should be taken in various locations throughout the house. In addition to meeting target weights. Uniformity is important.
