First, before you can set prices, you need to know your input costs. Cost of a chick, how much they eat to get to target weight, multiplied by the cost of feed, how long it takes to feed them, etc.
IMO, the 'general public' isn't your target market if you're doing this for money and not as an expensive hobby. If you raise your meat birds in movable pens on pasture, you can end up with a premium product and get a premium price. If you target people who know the difference, and are willing to pay for it, raising meat chickens can be worth your time. I've seen pasture raised, dressed frozen 5# chickens in the $15-$20 range, depending on whether they're sold on-farm or at a market.
