Free delivering

welfare
promise
While working to perfect house
design, management and
worker training, Iowa Cage
Free is striving to provide good
hen welfare and competitive
economic performance.
DEVEN KING

W

ith the U.S. egg-laying industry potentially
moving toward 100% cage-free production, new housing systems are being tested
to find what methods make the most sense economically, while providing for bird health and welfare.
Recently, Iowa Cage Free LLP constructed a unique
two-story, cage-free house for 540,000 hens.
Inside the outer skin of the building, walls and roof
are four housing enclosures or rooms. These rooms are
arranged as two stacks of two that are placed side by
side with air space in between the two stacks and over
the top of the stacks, which serves as a plenum for air
movement from outside the building to the inside of
the rooms. Each room is 100 feet wide and 640 feet
long and houses 135,000 hens. Each room has five
zones. The exterior dimensions of the building are 220
feet by 640 feet.
The birds can move across the 100-foot width of

the room, but each room is divided by fencing into
five compartments that are 128 feet long.

Equipment
Cody Lucero, business unit leader, Iowa Cage Free,
said success in the layer house begins in the pullet
house. Pullets need to be housed in systems that
properly prepare them for the environment they will
encounter in the layer house. Jump Start Rearing
System by Vencomatic was used before the birds were
transferred and adapted to the cage-free laying environment. The new layer house at the Goldfield, Iowa,
farm has Vencomatic Bolegg Gallery aviaries.
Iowa Cage Free has installed equipment from
several manufacturers in the company's houses. The
approach has allowed the company to evaluate each
system and better understand how the birds interact
with each system's design. Lucero commented that
