    So this is my forth round of hatching duck eggs (Cayuga and Indian Runners). I have this one Runner egg that appears to have no Air sac at all, but veins definitely are growing. Today would mark day seven of incubation. When I candled this egg I couldn't find a visible air sac at the bigger end of the egg, so I thought that maybe it was one of those ones that had the air sac at the wrong end. When I checked though, I didn't see an air sac there either. It's a little lighter in color at the narrower side of the egg but I'm not seeing a defined air sac. The veins looks like they're going towards the thicker end of the egg. Has anyone seen or heard of this before? What should I do?

    So the first picture is the thicker end of the egg (Where the "BR" is), the second one is the narrow end of the egg and the third is a view of the whole egg from the side. You can clearly see it's growing, and I can even see it's heart beat. The veins kinda just go down the side of the egg. You can see they kinda go to where the air sac should be but obviously you can't see one. If you want me to post a picture of one of the other eggs I have that you can see the air sac and compare it let me know and I'll do so.

    Okay so update, I've been checking that one egg every single day with no luck of locating an air sac anywhere. I candled the egg again earlier today and to my surprise I finally was able to see an air sac! However, it's on the side of the egg and not at an end and, it is very small; about the size of my pinkie tip. I've read up on detached air sacs, but this one doesn't seem to move when I move the egg. The air sac is closer to the thicker end of the egg. Could have it possibly been detached and in the middle of the egg for the first eight days of incubation then, decide to reattached today? Also, my eggs were not shipped, we picked them up from a local farmer. My questions now are:
    Do I need to keep the air sac facing upwards as it is right now or should I try to put the egg in a curtain position to try to get the air cell to move?
    Should I worry about the size of the air cell right now? (The humidity is currently set at 70%, raise, lower, good?)
    What do I need to do to help this guy make it to the hatch date? (April 13th) And if it does make it will I need to assist him/her with hatching since the air cell is not in the correct place?

    Other than the misplaced air sac the little duckling is doing great! Lots of growing and movement! :)
