A friend of mine gave me some fresh eggs from his farm to use for breakfast. My 11 year old daughter asked if she could take a few to hatch. I explained they needed to be fertile and they wouldn't be able to hatch but I let her try. She spent a few days with a light bulb then her older brother ordered her an incubator. I really thought this was not going to happen and I was just letting her try. Last night was day 22 and I told her they should have hatched on day 21 so it was over. I took one of the eggs out and tried to crack it to see what was inside. After a large piece of the outer shell broke off I heard chirps. It has 1/2 of the shell missing but still has a thick white membrane. Its still chirping and wiggling around but hasn't ripped through the membrane. I have no idea what to do and I feel terrible that I cracked the shell. I really thought this wasn't possible. I'm afraid to turn the egg onto the exposed side so I haven't moved it. I still am adding water to the incubator. There are 5 other eggs that show no progress of hatching. We are now on day 23. What should I do?
