Example: How long will a poultry building be when each lay cage contains eight birds and the
cages will be stacked 4 high per side. The house will contain 12,800 hens and is
configured as depicted in Figure 12.6 with 4 rows of hens.

Solution: Cage size, from Table 12.7 is 24” x 18”.

4 cages high x 4 rows = 16 cages.
8 birds / cage x 16 cages = 128 birds
12,800 birds ÷ 128 birds / stack = 100 stacks of cages.

Length of a stack is 24” L.
24” length x 100 stacks = 2,400 inches
2,400 inches ÷ 12 inches / foot = 200 ft cage length.

200 ft cage length + (2 ends x 10ft /end) = 220 feet length
