Art and science of rearing the newly hatched baby chicks
Care and management of young chicks for the first 3-5 weeks is called Brooding
Chick embryo immediately after few of hatching – Poikilothermic
Adult birds are Homeotherms
Chicken are PRECOCIAL (Young ones are relatively mature and mobile from the moment of birth)
Young ones have hair (down feathers), open eyes, developed brain and capable of walking
Average body temperature of newly hatched chick – 103.5ºF
Adult chicken – 105-108ºF
BROODING EQUIPMENT
1. Brooder – Heat source (gas, coal, IR bulbs, incandescent bulbs, kerosene or electrical stove)
2. Reflectors – canopy or flat type
3. Brooder / chick guard - GI sheet or card board sheet or asbestos sheet of 1.5’ height and 5, diameter is sufficient for 200-250 chicks
DEEP LITTER BROODING
Materials required
Brooder guard or chick guard
Brooder (heat source) – gas or electric bulbs or coal
Litter or bedding material – 100 kg per 1000 Sq.Ft
Old newspapers
Chick waterers
Chick feeders or trays
Thermometer
Lights
Side curtains
CAGE BROODING
• Battery brooding cages with electrical bulbs
• Gas brooders/ room heaters
• Use of circulating fans to distribute the warm air
• Gas brooders can be hanged in between the cages at a height of 9’ from the floor level with 3-4’ distance b/w the brooders
ENVIRONMENTAL CONDITIONS FOR BROODING
Temperature
Brooding is carried out 0-8 weeks in case of layers and 0-2 weeks in case of broiler birds. Heating is very much essential to provide right temperature in the brooder house. Too high or too low a temperature slows down growth and causes mortality. During the first week the temperature should be 95ºF (350 C), which may be reduced by 5º F per week during each successive week till 70ºF (21.10 C). The brooder should be switched on for at least 24 hours before the chicks arrive. Hanging of a maximum and minimum thermometer in each house is recommended to have a guide to control over the differences in the house temperature.
• 1st Week – 90-95º F
• 2nd week – 85-90º F
• 3rd week – 80-85º F
• 4th week - 75-80º F
• 5th week – 75º F
The behaviour of chicks provides better indication of whether they are getting the desired amount of heat.
When the temperature is less than required, the chicks try to get closer to the source of heat and huddle down under the brooder.
When the temperature is too high, the chicks will get away from the source of heat and may even pant or gasp.
When temperature is right, the chicks will be found evenly scattered.
Ventilation
• HDPE curtains should be hanged @ on the mesh
• Leaving one feet distance from the roof to provide cross ventilation
Humidity
Brooder house humidity ranges from 50-60 per cent. High humidity creates the problem of wet litter which leads to coccidiosis and low humidity causes dusty litter resulting in respiratory problems.
Lighting
• 0 - 14d – 24 hrs
• 3 - 5 wks – 22 hrs
• 6 –

Art and science of rearing the newly hatched baby chicks Care and management of young chicks for the first 3-5 weeks is called Brooding Chick embryo immediately after few of hatching – Poikilothermic Adult birds are Homeotherms Chicken are PRECOCIAL (Young ones are relatively mature and mobile from the moment of birth) Young ones have hair (down feathers), open eyes, developed brain and capable of walking Average body temperature of newly hatched chick – 103.5ºF Adult chicken – 105-108ºF BROODING
NATURAL BROODING ARTIFICIAL BROODING In the absence of broody hen Using artificial heat Equipment used – Brooders Heating source Reflectors Brooder / Chick Guard
HOT ROOM BROODING Central heating system provides heat for the chicks Hot water pipe @ 2.5’ above the floor level, 4-8 hot water pipes will be placed Pipes will be connected to a boiler placed outside the brooding room COLD ROOM BROODING Spot heating devices like hover with gas brooder or electric bulbs or Infrared bulbs are placed @ 3-4’ feet above the floor. Battery brooding Cages containing electric bulbs. TYPES OF BROODING
BROODING EQUIPMENT
BROODING EQUIPMENT
FLAT TYPE HOVER CANOPY TYPE HOVER
Charcoal or kerosene stoves are covered with plate or pans to provide supplementary heat to the chicks CHARCOAL OR KEROSENE STOVE
Natural gas or LPG is connected to a heating element to provide heat for chicks Hover is connected @ 3-4.5’ above the ground Measure the temperature @ 4” above the litter 30 kg of gas is required for 1000 chicks for 14 days Provides uniform heat If the temperature is high and chicks are feeling hot increase the height of hover (i.e., > 5’) GAS BROODERS
GAS BROODERS
Thermostatically controlled heating system connected Spreads uniform heat to a large area Avoids crowding of chicks under brooder directly One brooder for – 300-400 chicks (Or) Use of electrical bulbs connected to a hover Placed at a height of 2-3’ above the ground level ELECTRICAL BROODER
Self reflecting bulb One 250 watts bulb is sufficient for 150-250 chicks INFRA RED BULBS
Earthen pots of 6-10 litres capacity closed mouth pots are used Holes of uniform size are made at 1-2” distance leaving 1/3 from top One pot is sufficient for 600 chicks Pots are filled with burnt coal (0.75-1kg) before placing inside the brooder Additional pots are placed at a distance of 7-10’ depending on number of chicks and season Illumination the room with light of 40-50 lux POT BROODING / COAL BROODING

Automatic feed hoppers Nipple drinker
Provide electrolytes, glucose and vitamins in drinking water for first 5-6 days Preferably 8% glucose is added to stress and dehydration Avoid feeding for first 6 hrs, make sure of enough water provision observe the behaviour of chicks and adjust the temperature
Beak trimming (formerly debeaking) is the removal of approximately one-quarter to one-third of the upper beak, or both upper and lower beak, of a bird. Beak trimming is performed as part of an overall strategy to reduce peck injuries and death when raising groups of poultry. Beak trimming may be performed on many species including laying hens, turkeys, ducks, and quail. Feather pecking, peck injury and peck mortality (cannibalism) in poultry occurs at variable rates and may unpredictably become severe and cause high rates of distress, injury and death in a flock. Beak trimming is acutely painful, as nociceptors are present in the tip of the beak. M ethods of beak trimming - hot-blade, and infra-red BEAK TRIMMING
Vent pecking & Cannibalism Feather pecking
Hot blade beak trimming
INFRARED BEAK TRIMMING
Unhealed navels Leaky vents Common in the chicks offered feed immediately after hatch Yolk sac is not absorbed into the body properly Seen in E.coli infections
Dubbing Removal or trimming of comb Usually done in male birds To prevent frost bite and fighting behaviour
