Why will you pick meat birds? They are not very healthy, and they are babies when they die. Also, buying them as chicks supports factory farm companies that make them. If I HAD to eat chickens, I would eat gamier chickens that are healthy, that do not get to be 20+ pounds if not killed past baby age, or not starved. And they can raise their own chicks, protect themselves better from predators, do not crap nearly as much or as stinky, and they do not need to eat copious amounts of commercial grain - they can find their own food! Yeah, the carcass would not be obese and baby-tender, but it is more flavorful, more nutritious from the foraging the birds do, and kinder to the bird.
I have had half a dozen Cornish x as pets over the years, and even entirely free range, fed very little fermented feed, some days not feeding them at all, and letting them have 'regular' chickens as an example, they are not at all like my game birds, or even the dual purpose breeds. You would be doing chickens a favor by eating a real, healthy breed if you decide to eat them. Obviously you do not have to listen to me, but I just wanted to give you the other side of the coin on eating chickens.
