System Of Rearing

Layer type chicks may be reared on deep litter or in cages at all 3 stages
Most of the farmers rear on deep litter- brooding & grower and transfer to cage just before the age of laying
Design for rearing layer birds-deep litter widthnot mre than 24 feet (7.20 m)
Length vary depending on the required capacity
Walls : long walls on the sides should not more than  30cm(one feet) height above the floor level
Space between the top of the side wall and the roof should be covered with wire mesh,(1.25cm x1.25 cm,20-22 gauge thick) , weld mesh (2.5 x 5.0 cm,12-14 gauge thick or chain link( 2.5cm,12 gauge)
To prevent entry of rodents and predators
Doors may be fitted at every 8-10 m interval each of one meter.

Roof :
Thatched ,light-roof tiled or covered with asbestos or aluminium sheets
Roof Ht preferably 8-10 feet(2.4-3.0 m) at eaves and 12-15 ft ( 3.6 -4.5 m) at the ridge.
The projection of roof at eaves (overhang) should be at least 3-4.5 ft(0.9-1.35 m) on either side
Minimum distance of 100 ft between brooder and layer houses
Cage rearing – no side wall constructed
Number of building required varies depending on the length of interval between receipt of the chicks
Generally layer farm established  1+ 2 pattern ( chicks to bre received at 28 weeks interval), 1 + 3 pattern ( 20 weeks interval) , 1 + 1 + 5 pattern ( 12 weeks interval).

Fix the cages at 75cm above the floor level
Cage 180 x 90cm size(6’ x3’) & 30cm (1’) ht
About 100 chicks may be reared in it 160 cm2 space per chick
Floor made up of 1.25 x1.25 cm size welded mash of 16 gauge thickness
One 100 watt bulb is sufficient on the top of the cage for providing heat for Ist 3 weeks
Ist 2 weeks ,small feeders and waterers have to be kept inside the cage and afterwards they may be fixed outside on the sides of the cage
First few days it may be required to keep card boards on the sires of the cage to prevent chicks falling down the sides.
