About the "birds in a cup"
Wouldn't work, at least, not he way you're hoping. The cup (assuming semi-permeable membrane) may help with getting oxygen to both birds, but it doesn't have the minerals that are vital in bone growth. Chicks and ducklings actually absorb the minerals from the eggshell as they grow so as to develop bones properly.
Those Japanese students may have hatched a live chick, but I'm certain that if it lived past pipping, it had bone problems within a week.
Now, if you can figure out how to solve that, I'm quite interested. A simple addition of powdered eggshell? Lining the bottom and top of the cup with powdered, baked shell?
You may find this interesting: People studying embryo growth (check out quail/chicken chimeras; I believe that there's a video on youtube) actually remove a small portion of the shell, peek inside, and then replace the shell and membrane.
