Chicken meat without the chicken

Which came first, the chicken or the egg? Perhaps in the future neither will be needed because there's a $1M prize for the first to grow chicken meat in vitro in the lab. The idea sounds cool but at the same time feels weird to me. I can't seem to explain why. Meat that was never an animal in the first place? Hmm. I suppose that will mean goodbye to dark meat. Then maybe eventually chickens will no longer have to be domesticated--if we can grow meat in the lab, why not chicken eggs as well?--and will be left to fend for themselves in the wild.
