Too much humidity?

If you've read any of my other threads you know I haven't had the best of luck this year, but I have noticed something about my setup that doesn't exactly look like the majority of you guy's. I incubated the ball clutches the same way as I do my corns, only at 89 degrees instead of 81. They are in an air tight container with moist vermiculite. I do crack the tops on the containers once or twice a week for air exchange. I notice that most of the eggs you guys post close to hatching are fairly deflated. NONE of mine were. They were actually very full, to the point where when I cut them they squirted fluid out a bit. Could this be a factor in my "bad luck"?

Yes, they were not ready

Well, that could be true, but the first clutch that pipped on their own on day 60 were that inflated the day before as well.

I would recommend putting a thermometer inside the egg box to make sure that the temps are accurate. The temp of the incubator could be a little off depending on placement of the probe.

what thermometer would u guys recommend for an egg tub??

Just one that is moisture resistant. I personally use one made for inside fish aquariums.

Any reliable probed thermometer works well for keeping the tub temps where you want them.

Thanks, but that isn't my issue, hence the ? about humidity...
