Call Duck Eggs - Saddle Shaped Air Sac

[Adam Wyllie]

Evening All,

I am just looking for some advice.
I have just received 3 eggs posted, and I have candled them to look at the condition of them.
The air sac appears to be slightly saddle shaped (having done some reading about them).
I am leaving the eggs for 24 hour to settled before placing them into the incubator.

This is where I need advice.
I have seen that on a lot of the forums it mentions placing eggs in an upright position so that air cell can secure itself rather than placing the eggs on their side.
My incubator is a Brinsea Advance mini, so naturally the eggs would have laid on their side and be turned by the automatic system.
What is the best thing to do in this situation?

I should add the air sac although being saddle shaped was secure and not moving around the egg.
I have attached pictures of the eggs with the pencil outlines of the air sacs.

Many thanks for any advice.

Saddled air cells I never worry about doing on their sides. It's really only fully detached ones that should be incubated upright until the air cell can reattach.
