large air cell question

[faykokoWV]

I set eggs and we are on day 17. The eggs are from two different people. One set of eggs everything looks good, but the other set has very large air cells- almost 1/3 of the egg. They almost look like the aircell split because it make something like a two leaf clover pattern (sorry-its the best I can describe it)
Because the one set of eggs is fine, I don't think its my humidity. There are chicks in the eggs with the large cells, is there anything I can do at this point to help ensure they make it to the end without putting my other eggs at risk?

The bigger air cells ether were collected longer or spent time in a dryer climate. You should still be ok but if they dont hatch with the rest I would crank the humidity up to about 75 or 80.

So get the humidity up for the hatch date, then if these don't hatch with the others, crank the humidity up as high as I can get it. Should I go ahead and stop turning a day early and get the humidity up a little now?

Its been running a good average of 45% the whole hatch.
