I have over 300 chickens and I eat eggs every day, farm fresh eggs as the ones in stores are stored upwards to 3 months before hitting the stores..
When I was a yute, I raised and cared for about 2 dozen chickens and they kept us in both eggs and meat from when I was ten until I went into the Army and then my younger brothers took care of them until they too left home.
If you have a little space {we had 2 acres in the country} keeping chickens is easy and it saves loads of money.
