For the last three hatches in my incubator, my chicks were fully formed, or looked so to me, But died in the shell. I have a incubator that you can see thru and and egg turner. My incubator keeps beeping trying to keep temperature at set temp. I am on day 19, I took eggs out of turner, And so far nothing, Day 22. I am afraid it has happened again. This hatch. I even turned the eggs myself, about 3 to 4 times a day. Help! has anyone had this problem???
