i think that would be true because i had 3 shipped aggs that came in the mail. one of them was a lot smaller then the other two. out of the three only one developed fully so i broke the other two open to see how far they had made it and the smaller eggs chick was significantly smaller then the big eggs chick. that doesnt mean though that you should try it anyway. my son was premature and i still kept him lol! just kidding. well youll have to tell me how it turns out.
