I quickly made up this spreadsheet earlier today on poultry profitability. This does not include the price to build each chicken tractor nor processing costs. I plan on using the Joel Salatin model chick tractor and moving each tractor daily over a 5 acre field. I understand 1sq ft per bird is optimistic. May adjust that number. This is just a rough estimate but am I in the ball park here in terms of cost per bird until 10 weeks?
