the birds with the workers. In the rearing and layer houses,
walks should be performed multiple times a day at random
intervals, starting when the lights switch on in the morning.
Formulating a cage-free ventilation strategy
One thing farmers may overlook when designing a
cage-free house, Ament said, is ventilation and heat distribution. In a caged system, heat generated by the birds
stays in fixed areas, making for easier temperature control.
Now, the birds are free to move around and the centers of
heat generation fluctuate constantly.
For that reason, farmers need to consider how
their house design - including the use of catwalks,
manure belts and other solid obstructions - will
influence the air flow and ventilation of a cage-free
house. When ventilation - especially in the lower
levels of the house - is not sufficient, it can lead to
the creation of hot and cold areas that can affect the
bird distribution inside the house and contribute to piling.
Additionally, farmers need to consider if the strength of the
air flow, or the temperature, is negatively affecting how the
birds use the nest boxes and contributing to mislaid eggs.
Ament said ventilation is one of the things farmers are
likely to skimp on in order to cut back costs, but it must
be considered as an integral part of a successful cage-free
house. Ventilation should be carefully designed to react to
changing conditions in order to create the proper environment for optimal egg production.
