Due to increased exposure to pathogens and potential
disease vectors, pullets destined for free-range housing
receive more vaccinations. Some producers will add electrolytes, vitamins and minerals to the water at these times
to support their immune systems and reduce stress. Again,
ensuring target weights are met will prevent setbacks and
mean that, when transferred to the laying house, they are
in the best possible condition. As opposed to a cage environment, the birds will need to learn where the feed, water
and nest boxes are.

In many cases, the breeds used in caged and cagefree systems will be the same - with differences
down to country or company preferences. Brown
egg layers are more popular in Western European markets and
are often associated with free range. While white egg layers
are more common in regions where hens are caged, they can
also be kept successfully in cage-free systems.
Brown hens are bigger birds, with greater maintenance
requirements and poorer feed conversion than white birds.
