Chick hatching weight can be influenced by several factors, and each of the choices indicates an important aspect of the hatching process.

Firstly, egg size is a critical determinant; larger eggs typically contain more nutrients and provide a better environment for chick development, often resulting in heavier chicks. This is because larger eggs have more yolk and albumen, which supply the necessary proteins and energy for the developing embryo.

Secondly, the time between hatching and pulling delivery, which refers to how long chicks remain in the hatcher after they hatch before being moved, can impact their hatching weight. If chicks are allowed to stay in the hatcher longer, they may continue to absorb residual yolk sac, which can contribute to increased weight by the time they are pulled for delivery.

Lastly, egg weight loss during incubation, which is affected by humidity and temperature management, also plays a role in hatching weight. Eggs naturally lose moisture, and if this loss is too great, it can result in lighter chicks at hatching. Proper management of environmental conditions helps maintain an optimal weight loss rate that supports healthy chick development.

All these factors work together, demonstrating that multiple elements must be considered when assessing influences on chick hatching weight. Hence, the correct response
