Temperature Management Maintain sufficient warmth in the brooder before chicks arrival.
First week chicks require 35oC (95oF) warmth.
Reduce temperature of brooder by 2oC every week
Monitor the behavior and distribution of the chicks to assess the
adequacy of the warmth.
Crowd under the heat source
Low temperature.
Chicks moved toward periphery:
High temperature
Uniform distribution of chicks
Optimum temperature

Never recycle old litter for subsequent
batches.
Litter material should be kept as dry
as possible.
Way to control ammonia
production:
Remove the wet litter.
Rake litter every day in morning after
two weeks to break the caked litter.
Ensure proper ventilation.
Spray super phosphate @ 2 kg/10 m2
help to reduce ammonia level
Squeeze a handful of litter to assess
moisture levels in the litter:
