MaKomb Laying Batteries 
Sufficient experimental work has been carried out during recent 
years to prove that the Laying Battery method of producing 
eggs and meat at a minimum cost can be successful. In the 
MaKomb we offer the latest improvements in Laying Battery 
equipment. 
Lowers feed-cost. Reduced feed-consumption is assured and 
10 pounds of feed should be saved annually per hen. 
Labor reduced. With this new model 1,000 hens can be cared 
for easier than the same number can be taken care of in the old 
floor method. 
Automatic culling. It is easier to discover the non-producers 
and ailing fowls, with consequent greater opportunity to avoid 
total loss. 
Doubles capacity. For example, allowing the recommended 
4 square feet per bird, a house 20 x 60 feet should carry 300. 
Equipped with rows of 9 72-bird units, it houses 648, with wide 
aisles to work in. Buildings are a costly factor, and the securing 
of double capacity justifies the use of Batteries. 
All sizes (except 12-hen) are equipped with heavy canvas, 
rubber-covered belts.
