Not exactly speedy, are they?! Have cooked and eaten my dinner and he's still no further along! That's why i like incubating ducks, two smashes and they're out! Plus, I do NOT have the room for Emus!
Good luck!
BTW, what's the success rate of massive eggs like those? I can't hatch geese, big eggs seem to fail me. I'm at about 10% success rate on those.
