Turkeys hatching eggs

So have 6 turkey hatching eggs in incubator. Day 18, what way should the air sac be at the moment? Should it be taking up half of the egg in an up and down fashion around the egg ( if ya know what I mean). Advice plz?

If the air sac is taking up half the egg, I think that's too much.

It sounds like you may be describing saddled air cells? Pictures would be helpful.

Those do look saddled. Are they shipped eggs?

 

[Lisa_123]

Yes they are shipped eggs but got them special delivery so here in just one day. Does this affect hatching rate you think?do you have experience hatching these? Should I keep the humidity higher???

What % should I keep eggs at now, we're middle Incubation at present , day 18 , week and a half to go. Normally it would be at 50-55% humidity at this point , advice??

Can you reverse this? Can you decrease the air sac now?
