@dlowan,
Yes, it is why chickens are everywhere in the third world. They are the most cost effective form of meat. There are also problems with cattle, sheep and pigs depending on location (religion, climate, feed, etc) but chickens are quite adaptable and although they have feathers, they dont waste protein on large bones.
I think steak will be the most economical to produce first. Especially in countries like Japan who import it and sell it for over $100 a kg. So steak in certain locations, I think will be first.
