Keeping your own chickens and harvesting their eggs is a step towards being able to feed yourself during tough economic times. In addition to the food value of the eggs, there is the economic value in the ability to trade some eggs for other items and having something to trade may be worth more and more if the economy keeps on sliding as food prices keep on rising.
You will also have the chickens which you can trade if it is absolutely necessary to do so.
before going out and investing in laying hens and the material for the
chicken coop, do your homework; learn as much as you can about all
aspects of raising and caring for chickens and as I said near the
beginning be sure you can keep them where you live and if you can follow
the bylaw to the letter.
How many chickens will you need? Well, that depends upon your egg consumption; so many eggs does you family eat each week?
may find that one layer lays one egg per day, so if this holds true
then 4 layers means four eggs per day which quals 28 eggs per week which
will be more than enough for a family of four.
