Meat from free-range chickens has an ecological footprint about 4 times higher (they grow slower, live longer, so need more water and feed, while excreting more methane, and use up more land).
It would indeed be interesting if packaging from supermarkets put some estimate of environmental footprint on the packaging. I doubt it will happen: It would thoroughly confuse many consumers that the product with the highest price has the worst environmental impact, and could reduce sales of their highest margin products.
