Update on the duck eggs – one of them has done an internal pip!! I candled the egg around 9pm, and could see the shadow of a duck bill moving around in the air sac on the blunt end of the egg. So eggciting!! 🙂 Too bad I do not have a picture of this, as I didn’t want to risk having the egg out of the incubator too long or accidentally drop it while trying to get a good lighting angle.
Unfortunately, the other eggs don’t look as developed and seem at least a day or two behind. The air sacs are smaller in those eggs but I can definitely see movement in them when I shine the flashlight at a certain angle.
Once the duckling has done an internal pip, it should be able to breathe and start making peeping noises, but I haven’t heard anything yet – still, it’s very encouraging!
I removed the egg turner tray (the black frame thing) from the incubator yesterday, and this evening I removed the incubation tray, and replaced it with the hatch tray. The hatch tray sits several cm lower in the incubator as compared to the incubation tray. I suppose it’s to allow the hatchlings more space to move around or stand up without hitting their heads on the “ceiling”.
