Housing: The design, construction and management of a poultry housing system must
meet the birds' need for shelter against undesirable environmental conditions such as
extreme cold, excessive heat, rain and wind and modify these climatic conditions to
conform to an adequate environment for laying hens. They shall be constructed to
minimize transmission of disease, parasites and other vermin infestation and optimize
the principles of disease prevention. The housing should also protect the birds from all
forms of predators and allow for daily visual inspection and care. Public Act No. 117 of
October 12, 2009 will require that by April 1, 2020 all egg laying hens be housed so that
they are able to fully extend their limbs and turn around freely. Hens may be housed in
a variety of housing arrangements such as aviary, single tier systems or colony systems
that are large enough to do so with a minimum of 1 sq ft per hen.
Housing in cages: Cages shall be designed, constructed and maintained to avoid
injury to the birds and allow bird comfort and health. The cages must be so constructed
as to allow the safe placement and removal of birds. Cage height shall allow a
minimum of 14 inches with a floor slope not to exceed 8.5 degrees. As stated above
conventional battery cage systems will be eliminated as a housing option on
April 1, 2020.
