The feedstuffs must be thoroughly mixed with a shovel or in a home-made mixer. It can be made from a drum. Also a cement mixer can be used.
Do not store your feed for too long
Weevils will quickly destroy your feed
Ingredients and the mixed feed must be stored in a dry place and safe from birds and rats
6.1 Choice feeding
Sometimes it is better to let the birds select their own feed and balance their diet themselves. This is called choice feeding or self-selection. Feed ingredients are not mixed together but are placed in separate feeders (about 3) and the chickens in this way make a choice. There are only certain situations where this can be done, usually when the birds are on the ground or the floor.
Sometimes a grain balancer ration is available from the feed mill. This special feed (high in protein) will allow local ingredients to be used and the balancer meets those

nutrients that are still deficient in the locally - available ingredients. This allows the birds to select a complete diet.

7. HEALTH AND DISEASE PREVENTION
Chickens are fragile and can get sick very easily especially when young
There are two major sources of disease.
Diet if not correctly formulated can result in the bird getting a metabolic disease due to a nutrient deficiency (vitamins or minerals) in the diet
Other diseases are caused by minute organisms called bacteria and viruses. It is often necessary to treat the chicks as soon as they hatch with a vaccine which allows them to resist the disease if it occurs. This is normally done at the hatchery. Newcastle disease is present in many countries and chickens need to be vaccinated more than once (see section 7.1)

Remember that “prevention is better than cure!”
Many diseases can be prevented by keeping your poultry house very clean
Overcrowding of birds can cause disease
Do not allow other poultry on to your farm (e.g. neighbour’s scavenging chickens)
Do not allow other poultry farmers to enter your shed
Place a foot bath with a disinfectant in it or limestone outside the door of your poultry house
Have a special pair of boots/shoes that you will use only when you are working in your poultry house
Leave sufficient time between batches of birds to clean the house and get rid of diseases that need to have a bird (host) to survive
Remove old litter, dirty bags and contaminated rubbish and dump them far away but in a responsible place that will not contaminate the environment
Discard damp, old feed. It can grow mould which can produce toxins. They can kill or make your chickens sick
All in-all out systems in which all birds are the same age help to reduce disease
fleas can make your poultry feel uncomfortable. This will affect their growth rate and egg production
Insecticides are used to treat the infected birds. A dust bath will also help to reduce these external parasites
Internal parasites such as different worms and minute protozoa causing coccidiosis can be prevented by medication
This is done routinely by adding a coccidiostat to the mixed feed for broilers
Remove immediately sick birds and bury dead birds.
Never eat or sell sick birds; they will make your family and others ill
7.1 Newcastle disease
There are two diseases that are particularly dangerous in many low-income countries. Newcastle disease (ND) is endemic (always there) in many countries and becomes active particularly at the start of the wet season. It can wipe out entire village flocks although a few individual birds often do survive. There are now ND vaccines that will withstand the heat for a short period (thermostable) of time. Vaccination is most effective by eye drop and birds should be vaccinated a month before expected outbreaks by a trained person. There is also a need to treat the birds at intervals through out their life. This is a specialised area and the poultry keeper will need help from experts but it is well worth the effort and the vaccine is not expensive.

7.2 Avian influenza
The H5N1 strain of highly pathogenic avian influenza (bird ’flu) is particularly dangerous not only because it can infect different poultry species and wild birds but it can also kill humans. Village poultry are especially at risk because they are outside and may be in contact with wild birds and other poultry species (ducks, geese). The disease spreads rapidly through the poultry flock.
The virus can be spread by eating infected birds and can kill the consumer particularly if she/he is young. Household poultry keepers should keep themselves informed about the situation in relation to bird ‘flu as it often appears at particular times in the year.
