this is my first time trying to incubating eggs I have two cortex quail eggs about 6 days old and 5 days old. I see veins and a dark area that takes up the majority of the egg, but not till today did I see shadows moving around in both eggs. im worried since they were completely fine yesterday. I was tried to keep one of the egg completely still for a while and the moving didn't stop. what is going on? are they still alive? I was really looking forward to having little baby quails.
