There really isn't anything you can do. The vast majority of chicks can hatch on their own even when their air cell ends up in a weird spot. If possible I would lay them on their sides to hatch with the air cell pointing upwards - that way it doesn't matter which way they have decided to orientate themselves (pointing towards the fat end or the narrow end of the egg), if there is any excess liquid in the egg there's less chance of them being affected by that if the egg is laying on its side.
It's possible they may pip straight out rather than pipping internally into the air cell and they may do that at the narrow end of the egg. In that case the time they would have stayed at the internally pipped stage is added onto their externally pipped stage so they can take up to 48 hours to hatch out, but most of the time they can hatch all by themselves just fine. It's just a case of keeping an eye on them and judging if they end up getting stuck as they unzip (my little one that did that needed help right at the end).
This is an excellent source of information I found in the Goose forum. It applies to any incubated bird egg and might be worth a read through:

One part explains about how to judge whether the chick/duckling etc has fully absorbed the remains of the yolk if you do need to assist.

for your eggs and do let us know how it turns out.
