It is recommended that poults be provided one linear inch of feeder space per bird and have feed
available at all times. As the poults get older, feeder space may need to increase to 2-3 linear inches
per bird.
o
Heat lamps are not required if the ambient mean temperature for the area is 75 F. When the
o
temperatures are 65 F and below, heating is required for chicks and poults, depending on age. Heat
lamps are raised as the birds age and grow bigger as their body heat will compensate. It is important
to monitor the room temperature to assure the birds viability. Consult the Chicken Heat Table 12.4
when determining if your chicks still need a lamp
Turkey poults do better with brooder temperatures at 95-100 degrees for the first week, then
lower the temperature by about 5 degrees per week until
they are fully feathered, approximately 6-8 weeks old.
They will still appreciate a heat lamp at night for a few
weeks after this period if the nights are cool. These are
recommendations that are dependent on elevation and the
time of year.

Table 12.4 Chicken Heat Table

Chick Age Temperature

0-7 Days 95°F/35°C
Week 2 90°F/32°C Figure 12.2 Heat lamps provide
Week 3 85°F/29.5°C warmth for chicks and poults
Week 4 80°F/26.6°C

Example A: 3,000 fryer/broiler chickens will be reared in a grow house that is 4,500 square feet.
Feeders cost $16.99 each, waterers cost $7.95 each, and heat lamp with bulb costs
$15.00 each. Use Table 12.3 Planning Equipment Space Requirements. How many
and what is the cost of (a) heat lamps, (b) feeders that are 38 inches in circumference
and (c) waterers with 24” circumference.

Solution:
a) # of Heat Lamps = space square footage ÷ 100 square ft/lamp

= 4,500 ÷ 100 square ft/lamp

a) # of Heat Lamps = 45 lamps

Cost = Quantity x price per unit
= 45 x $15.00
Cost = $675.00

b) # birds x Space/bird
Number of feeders = —————————
Feeder Circumference

3,000 x 3”/bird
Number of feeders = ———————
38” / feeder

9,000”
= ——————
38”/ feeder
= 236.84 round up

b) Number of feeders = 237 feeders
Cost = Quantity x price per unit
= 237 x $16.99
Cost = $4,026.63
