I almost always consider my hatch over by the middle of Day 22. Most of the birds who manage to hatch after that seem to have issues. The last one had intestines on the outside of the body and didnt live long. Plus, if they are alive and continuing to grow, they have probably grown too large for the egg and won't get out anyway.
I'm stuck on this too. I'm on Day 26 so completely gave up (I found out the temp was prob too low), but when I opened one of my eggs at the air sac end, the chick is alive inside! eggsrcool was helping me. I have 2 more in there with it. I'm scared to do anything now they'll probably still be there at Christmas!!!
