You have the ability to get fresh meat at the cost of gas by getting free animals off Craigslist. If animals are not free you may be able to get them for a few bucks. This takes money away from (((supermarkets))) and it's cheaper for you.
Depending on where you live, the animals will be fed and treated better than industrial farms.
For anyone hoping to have a farm with livestock, this is also good practice for slaughtering. One chicken slaughter can give a week of food or more by using varying recipes with the different parts.
