I just broke open a "clear" on day 12 (the first of probably 3 eggs that are not viable of the seven I set in a BMA.) I played brain surgeon preparing to drill a hole in someone's skull...got on laytex disposable gloves, got my little drimmel out and attached the drill bit attachment. I carefully and lightly drilled the cleanest little hole in the shell above the air sac, which I was careful not to pierce. Then I sniffed warily and was relieved to find no smell. This egg was 10 days old at setting

and had not developed at all in twelve days. With a sharp knife, I carefully reduced the shell around the outer thick membrane, then removed more of that thick membrane, and finally moved the inner membrane half away from one side of the hole I had enlarged, and slid the egg's contents into a dish. There was not any veining (red or otherwise) but I believe it was originally a fertile egg by looking at it. The yoke ran but had no eye spot or signs of early death I could identify when it went into the dish. No bad smell at all on this egg. The above was really a practice should I ever have to assist a latecomer chick who can't (wouldn't) make it out on its own. I know there are folks on both sides of "to assist or not to assist," each with sound reasons for their position. If it comes to it, I think I will be in the"assist when patient waiting fails" camp.
