"Qualify Pullets Determine
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.
la addition to meeting target weights, uniformity is important. Eighty per
cent of the birds should fall within a range of 15% above or below the average
weight. For example, if the average is 2.5 pounds, then 80% of the pullets should

weigh between 2.22 and 2.88 pounds. As the percentage goes above this point,
peak lay and total production of this flock will usually increase. Use of the
Purina’ “Body Weight Analysis Chart” (PS76O) (Figure 1) helps quickly to
determine the percentage of the birds within the weight range.
If the required nutrients are being-supplied, lack of uniformity in body size
may be caused by one or more of these factors:
1. Disease during the rearing period.
2. Chicks from different age breeding flocks
3. Crowding during rearing
4. Inadequate feeder and water space
5. Poor management during brooding
6. Improper debeaking
7. Insufficient light over the feeders and waterers.
8. Heat «tress.
