I didnt see that this was moved just yet to the other forum. That egg looks fine from the picture - usually the egg gets much darker during development so the later in the hatch the more difficult it is to actually see anything. The veins are likely no longer visible. Did you see any movement inside the egg - that is the test at this point. If you continue to see movement (the dark blob will move inside the egg) if you turn it slightly you will get some movement when candling the egg.
