What I did was scratch a small hole at the large end of the egg (where the air bubble is). I did this by scratching a X until a small hole formed in the middle of the X. Then I carefully opened a tiny hole in the shell, and carefully broke the membrane under it. Then I had a very small hole right at the bottom of the egg. I used a torch light to look through the hole and saw the chick breathing under its membrane. Since I knew it was still alive I put a small patch of wet toilet paper over the small hole and put it back. This is a pretty safe method since it doesn't harm the chick nor really interfere with it a lot. But you have to be 100% sure that the chick is late, if it was still in the embryonic stage it might get a bacterial infection and start rotting because of the hole. So if I were you I'd only try this on those 2 egg which are already two days too late. Give the others some more time. 1 out of 11 is a very low number and I'm sure if one chick made it there is another somewhere that will also make it.
Good luck with your unhatched eggs.
I was wandering if there is a (safe) way to crack the egg and see if there is any chick in there for 3 eggs its a day past and for the other eggs its 2 days past. And there just ameracauna mix eggs I took outta the coop from my chickens so not a big deal but want to know if there is any way I can brake the egg...thanks
