Unless you know what you're doing, don't. I have found a paper on 'safety holes'... very interesting.
One could argue that chicks that are not strong enough to get out of the egg by themselves should not survive. I have a different opinion. To me all life is precious. So if I can save a chick by helping it, I will.
The 'safety holes' are used when incubating rear and endangered bird species. It increases the chances of survival in the fiercely process of hatching. Yet one has to be extremely careful. It happens easily that a chick get's injured. This video is about the hatching of my emu eggs, the second largest eggs in the world. (and the most beautiful ones :) The first Emu chick got out all by himself. The second one needed a little help.

Text in this video:
Seven weeks earlier: For seven long weeks, I had no idea If these eggs would contain life They needed to loose 10% of their weight So I checked them Every egg every week With a smaller egg it’s easy to check for life This time that was impossible Because the shell was way too thick to shine through I didn’t see anything Finally after seven weeks I could try the ‘water trick’ My hope was that at least one of the eggs was alive And now, now I could finally find out So, fingers crossed Will they move? Hmmm… The first 4 eggs I tried, didn’t move at all Nr 5 Oh yeahhh And nr 6 as well! Why always the last ones? Some day’s later the most heartwarming thing happened Did you see that? The next day the reaction to my whistle became stronger The next morning Yes! First crack I was very exited Yet it took another day before it went further Two days after the first crack, I thought now we were almost there But it still went slow And the other egg (nr 6) started to worry me It was still reacting to me, yet lesser and weaker The chick seemed to be too weak to crack the shell Weaker chicks might die at this point There isn’t much you can do But I study eggs :) And I had found a most interesting paper A study on ‘safety holes’ The idea is simple: by very carefully making a little hole… Inside the ‘air chamber’, the chick can breathe oxygen and gain strength First I had to be sure on which side to drill, so I listened Now I needed to work very carefully I started at a natural spot “Yes, yes, I know…” The shell was a lot harder than I had thought it would be It took surprisingly much effort There is still a whole net of tiny blood vessels surrounding the chick Loosing a drop of blood from one of them is not a problem As long as I don’t shootout Good… Now it can breathe Almost immediately it sounded better, stronger I used my phone to record its sound When I returned at the incubator, the first chick was already out of its egg So I put it in an old incubator to dry The ‘safety hole’ proved to be very effective So a short while later… This one went a bot quicker now, but it still took some hours Here are the highlights In nature it would be under a giant bird right now Over here it needs a little help to get rid of the last parts So now I have two baby emus at home Might need to look for a bigger house soon
