weeks.
Reasons:
replacement pullets are expensive
egg production drops when hens get old (i.e. production is less than 1 egg/2days (uneconomical)
egg shells will get thin and break when birds get old
may be economical to put hens through a second laying cycle
hens are put out of lay by feeding a poor-quality diet for 3 - 4 weeks when about 60-70 weeks old but must always have water
very few hens will be now be laying. They are then put back on a layer diet and will come into lay 2-3 weeks later
eggs will now have sound, hard shells
hens will lay more eggs than before and for at least the next 20 weeks
will lay large eggs
Disadvantage: hens are out of lay for about 3 - 4 weeks during moulting and come into full lay over the next 3 - 4 weeks so there will be loss of income

9.8 EGG QUALITY
9.8.1 Internal
eggs get stale quickly in hot weather
store eggs in a cool place
when the egg yolk spreads into the white the egg is stale
a stale egg may not taste different from a fresh egg
some people like eggs with a deep orange-yellow yolk
others like the yolk a pale yellow colour
colour can be measured with a yolk colour fan
there are sometimes blood spots in the egg yolk but we are not sure why
41
9.8.2 External quality
eggs can be misshapen, soft-shelled, with pimples and rough surfaces
egg breakage occurs easily especially if the hens are old
these eggs are classified as seconds and fetch a much lower price in the market
dirty eggs, blood stained eggs and fly marks on the shell make the eggs unattractive to the customer should be cleaned before selling or eating
consumers prefer eggs that are either white or brown shelled but both have the same nutritional value

10. RECORD KEEPING
It is essential that you keep good records of feed consumed, eggs produced, bird deaths and removal of sick hens and non layers. A sample record sheet is given so that you can know accurately how your flock is performing.
[Example of a layer record sheet at the end of this manual]
11. CONCLUSION
Keeping poultry is not easy. It is a learning process. You should start slowly and expand as you gain experience. You may have set backs but you must persevere and seek advice when you have problems and need help. If you are kind to your birds and treat them well they will respond.
12. FEASIBILITY STUDY
Before you decide that you want to become a poultry farmer you must undertake a feasibility study that is researched thoroughly into all aspects of meat production or egg production to determine if you are going to make a profit. Otherwise you may be wasting time and money. When you have done your research you can then make a business plan. Your business plan will allow you a better chance of borrowing money from the bank to get your enterprise started. The most important question is, do you have a market for your produce?
