As the presence of a shell is involved in gas exchange, mineral enrichment and control of fluid loss, not to mention a resistance medium which triggers the hatching mechanism, I should imagine the success rate is extremely low and the resultant chicks, weakened both physically and in regards to immunity. I know they also hatched quail using chicken egg shells as a culture medium and that was more successful as the chicks were still able to absorb minerals from the shell but viability rate was still very low. It is a fascinating subject, though, as so many scientific experiments are, morally questionable, depending on your outlook.
However, my comment to the OP, with all due respect intended and with no malice at all, these experiment were all done under highly scientific conditions so the 'average Joe' is not going to achieve success in a non scientific environment...i.e. a cup, some clingfilm, a kitchen and a complete lack of scientific knowledge...so I'm afraid your 'want' will remain wanting. Please don't think I am criticising, it would be truly amazing to be able to see all that development going on in front of your very eyes, but sadly, I think a fully equipped laboratory would be the minimum requirement. The video gives the impression that these were just a bunch of school kids doing it in a classroom but they were in fact science students with all the resources of a top lab at their disposal. Sorry to say, us mere mortals will have to stick to incies or broodies xxx ;-)
