There were still 12 eggs remaining in the incubator yesterday. My father who raised pigeon for many years told me to open the eggs whenever it pecked or not. I did that. 6 survive, and 6 died.
I just wanted to tell you what my faterh in law told me and what I did.
I candled the eggs and found where the air cell was. Then use a ballpen to break the shell a bit above the center of the air cell. After that I used the toothpick to open the eggs, only the part above the air cell, very carefully. Then I see if the eggs/birds still were alive. If there was a bird alive, and I could still see the vas under the velum, I just left them in the incubator. And my father told me to give one or two drops of milk or glucose water to the bird's peak, giving the energy to the weak birds. After the vas was dry, I would do the things below. If I saw the vas was dry under the velum, I used the toothpick to break the velum, and helped the bird's head out of the shell. This step is very important. My father told me not to take off all the shells, just help the head out and let the bird get out completely by itself. This is the first time I did that. If I can do more carefully, I think I can save more birds. As some of them were hurt and brooding when I broke the velum. Becasue some vas were not dry completley when I did that.
What I think is that did help me to get more birds, especially when hatching the eggs by shipping. I ordered quails eggs on
ebay before, and just let the birds came out by themself. And finally I got a lot of birds dead in the eggs, even they alread pecked the shells.
That is just what I did today and hope that would help. I know many pepole suggest not to do anything for help. But I think if we do somthing, at least, we can give them some chance to survive.
