How to place eggs in lockdown?

[farmgirl2013]

My 1st time & I have 24 cayuga duck eggs on day 24. I just found that 3 of them have poked cracks & holes in their shells! Upon candling, I see about 80% are internally pipped, moving & chirping. I've taken them out of turner, but my question is how to lay them on the wire? I read that the lowest end of the air sac should be facing up, but that puts the cracks facing down. Which is more important to be facing up? Thanks!

Place them on their sides and tilt them slightly so the crack is clear off the bottom of the bator. Then crank up the humidity. Adding wet sponges or a damp towel to the incubator will help get it up quickly. Good luck with the hatch!
