As an FYI for future planning, ... I bought several 7.5-8.5lb roasters in the grocery store for about $11-12/bird. About what would it cost to raise roasters of this size? Or, if its not possible to give a cost due to wide variations in the price of feed, how much feed would it take? I like larger chickens because I have a large family and if I only have a 3lb bird I end up having to cook 2 of them. I also prefer the firmer texture and richer flavor they get from being older.
