Place 3-4 layers of paper above it.

Place feeder and drinker as required.

Manage ventilation lower and upper to

remove ammonia gases.

Brooder Management

Hover

temperature:

2 watt per chicks

500 chicks per hover

Note: Heat the brooder

12 hr before the

arrival of chicks in

summer and 24 hr in

winter.

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
