Animals should be at the desired target body weight according to their age. For this reason, starting from the 6th week, they should be weighed to decide on the transition to the next feed. If pullets are below the target values, layer chick feed can be continued until the 7th or 8th week. If they are close to the target values, they can be switched to grower feed. The transition from chick feed to layer grower feed should be made in accordance with the instructions of the parent stock company to which the chicks belong. This transition must be done gradually over one week by mixing the old and new feed. Otherwise, sudden feed changes cause stress in pullets. From the 6th week onwards, animals should be weighed at least once a week and the results recorded. Avoid carrying out vaccinations and feed changes at the same time. It is desirable that at least 80% of the flock has the same body weight (uniformity). During this period, the higher the feed quality and management practices applied, the better the peak production will be in the laying period. A flock with low uniformity cannot reach peak performance.
