Since it might be weird to somehow have the existing cows produce meat, many people seem to want more food factories (not sure about this myself lol), and in my opinion anyway, the poor pigs are overworked and very slow, maybe we could try turkey sheds!
Turkeys could grow quite fast (maybe 2 hours), make hilarious noises, and then discretely leave little plates of turkey breast or slices. Would lend itself well to existing factories, even more so to a dedicated sandwich shop, be awesome for special holiday menus.

Come on Playrix, give us more critters! We need turkeys!

P.s. The perfect sandwich shop would use a variety of breads, and have veggie options as well, but hold the butter maybe (takes too long)
