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.
Well they are expensive these days, chicks are $6 plus up from 3ish per chick just this year and higher and feed is $18 plus a 50lb which for me is $80 a day and chick grower is $25 a bag... And only going up and up.
