Candled Muscovy eggs today - Day 21 I think. Had to remove one but have 10 developing well. Question is that one of them has the air sac on the opposite end as the others (smaller end). Will it be able to develop this way and will there be potential hatching problems with this one?

I haven’t incubated one like that yet
My girl did lay one a few weeks ago but I didn’t put it in
I did however have a duckling from the school I let hatch that ended up with two air cells there was only one when they started
Because of this he had little room to grow and was not able to turn to hit either air cell. I saw bruises on egg and had to assist. Unfortunately his neck developed wrong and at 4 weeks I had to put him down. This is different from your story as your duck still has room in the egg with only one air cell
But baby may or may not go to the wrong end to pip
Watch for bruising and assist if need be
I think it should hatch and be just fine :)
 
I believe they normally can hatch just fine. But might have a little more difficulty if the egg is more pointy, rather than being more round. But as @New duck mommy 2021 said, watch for bruises on other areas of the egg when it gets close to hatch time, if the duckling happens to get positioned incorrectly.
 
This is pics of both sides of the Muscovy egg I am concerned about. Air sac is in small end. More than a week away from hatch date. I am debating just removing it rather than risk hatching an unhealthy duckling, or leaving it and being prepared to assist. I would appreciate others thoughts.

I had a duckling hatch from the wrong end not in the air cell she is 5 months old and perfectly healthy
Laying eggs already
It’s not my egg I can’t tell you what to do but I have assisted 3 out of my first 5 as they were small eggs and all are very healthy ducks never had issues and all were out of the bator in 8 hours or less as they were running around
I myself feel comfortable to assist and wouldn’t stop this egg from growing
The one I told you about earlie had two big air cells blocking his growth area
It’s very unusual
If you decide to keep it going
Watch it close at hatch time. See a bruise then make a safety hole in the bruise. If it internal pips in the air cell I would make a safety hole after 12 hours instead of 24 if it hasn’t external pipped as it will have less air
Or just let nature takes its course

Is this in an incubator or under a hen?
I ask because it looks so dark, but I know my ducks eggs get kind of dark after they bathe/swim, then sit on the eggs. But I don’t think I’ve ever seen one look like that from an incubator. I assume you can still see the duckling moving inside?
 
It is under a duck. One of 10 eggs from same clutch but the only one that looks like this. It is Muscovy so long hatching period. It is still 8 - 10 days away from due date. It is quite dark inside but still have an intact, clearly visible air sac in the smaller end.
