should i increase humidity?

[yuaan]

i am incubating 2 cream legbar and 2 dark chocolate eggs and today their 17th day started 2 hours ago . After taking marking on the air sac i realised that the air sacs are not as big as it should be but its big like it should be on day 14. I have incubated me first 2 batch ever using dry incubation. Although i had 100% hatch rate but i had to help lots of chick out of the eggs as they were mispositioned.
So this time on my third batch i decided to have a little bit of humity and i kept it between 35 to 45 %. But despite this the air sacs are not expanded as they should be.
As the eggs are wiggling on day 17 . Is it adviseable to lock the eggs down day early and high the humidity to 60%?

I would. There are a lot of different opinions on dry incubating but it doesn't sound like a good idea to me.

Just an update and a problem all 4 of the eggs are wiggling. One of the egg air sac has increase dramatically compare to the others. Hunidity is around 63% . Or tge chick is shrink wrapped as how can a air sac increase in ine day especially the humidty is high in incubator
