Site Selection
· Location should be dry and flat
· Poorly drained sites should be avoided or alternatively the house can be elevated from the ground
· Select a secure site away from predators and thieves
· In rectangular houses the end walls should face an East-West direction
· Clear all grass and bushes for about 3 meters on all sides of the house to keep away rodents and reptiles
· Ensure winds ventilate the house without causing draughts (cold)
· To protect against build-up of disease causing agents and parasites the house must be easily accessible and easy to clean
· Poultry houses should have openings on either side for ventilation
· A hole or ridge on the roof will ensure proper ventilation and give light
Housing Chicken
Building Materials
Use locally available material like timber, iron sheets, off-cuts and/or clay bricks
Remove all barks from wood to reduce the parasite load
Floor
Use slatted or raised floors to remove droppings and avoid predators
Remove any sharp edged objects from the floor to prevent possible injury
A concrete floor is recommended for easy cleaning and disinfection
Litter
Litter should be provided on all deep litter floor systems and laying nests. Types of litter include:
· Wood shavings
· Shredded paper
· Hay
Lighting
· Mostly important for laying hens in controlling number and weight of eggs
· Light intensity should be such that a person can read a newspaper at the centre of the house
· In a crowded house, transparent roofing sheets should be fitted to improve lighting
· Excessive lighting may lead to cannibalism and other vices

Perches
· Perches are important for chicken to roost on at night and during daytime.
· They also reduce boredom, which can lead to vices like pecking and fighting.
· Each one-meter perch may roost five adult birds.
· Perches are best made from rounded sticks, which match the size of the birds’ feet
Laying Nests
Laying nests ease egg collection and help avoid dirty and cracked eggs and should be provided at the onset of laying (18 weeks of age).
· Avoid placing nests on the ground or outside the chicken house as this will expose the eggs to predators and thieves
· Remove eggs continuously from the nests to stop hens from going broody
· Nests should be placed inside the chicken house and preferably above the ground
· Provide one laying nest for every 5 hens
· The front is about 30cm high and the back 45cm high
· To prevent egg eating, laying nests should be placed in dark areas of the house
· Brooding nests are individual nests and should be placed in quiet and dark places where they are easily removed for cleaning
Once the hen is broody it may be necessary to move her to an isolated place to avoid other hens disturbing her or going broody as well
There are two types of nests:
1. Communal nests (more than one hen sharing)
2. Individual nests where one hen lays at a time
Bio Security
Biosecurity is a set of management practices which when followed, reduces the likelihood of introducing or spreading disease causing organisms Infectious agents can survive for a certain period in the environment and spread via persons, animals and materials that might carry the agent.
Common Bio-security Measures
Location: Avoid There are two types of nests:
3. Communal nests (more than one hen sharing)
4. Individual nests where one hen lays at a time
5. Locations close to existing premises (between farms 500m-1km); Use prevailing wind directions when planning to minimize risk of airborne infection.
All-in-all-out: Reduce buildup of disease causing organisms by breaking the rearing-cycle for different ages.
Litter disposal: Remove used litter and properly dispose and disinfect it.
Site security: Reduces possible introduction of infection to premises mainly from personnel moving between houses and flocks, equipment and other innate objects. Use foot and vehicle bath.

Equipment
Feed troughs should be provided in the house. Naivasha chicken long feeders have proved suitable and economical. Round plastic or metal trough feeders are available and good but may lead to feed wastage.
• Feeders should be filled to about ½ to 2/3 full Age Space1-10 weeks 7 cm per bird11-78 weeks 12 cm per bird
• Feed without restrictions .Avoid feed wastage
