This is a really great idea, in my opinion. One alternative approach is breeding for lack of pain and happiness. We have made chickens much larger and lay eggs much more frequently. It is also possible to have animals that do not feel stress, anxiety, or suffer with enough breeding. If we identified gene variants associated with these, we could speed up the process with gene editing or some other tech.
