The first 18 weeks of a chick’s life is the most critical and will impact future production. Errors made during this time are difficult to overcome. During pullet development, their body is focusing on growing and building reserves for future laying. Low egg production and poor shell quality during lay can often be traced back to pullet development. Pullet management is essential for the success and profits of the future laying flock. The overall aim of pullet development is to reach a target body weight with high uniformity. Less than 85% uniformity will cause a decrease in egg production and peak production will be hard to maintain. Understanding developmental stages, maintaining brooder temperature, providing enough space, and providing fresh, balanced rations will help ensure the success of your future layer.
