Incubation!

[usmanshahzada]

I have placed 8 eggs this time again in that incubator and today is 5th day. This time maintaining humidity of around 50 degree this time. Is there anything else I should do? Plus sometimes humidity falls to 31 degree and then I add water to increase it back to around 50, does that make any difference?

Your humidity was likely way too high. Did you candle the eggs to make sure the air cells were the right size? I personally have to run about 30% humidity all the time to make sure the eggs have an appropriate sized air cell.

Your temperature sounds good. Have you calibrated your thermometers? You should have more than one. What level are they compared to the eggs? All of those could wreck a hatch.

I placed 8 eggs in the same incubator and this time humidity is around 50 degree and today on 5th day when i candled them using my phone's flashlight this is how it look like

You say 50 degrees, is that a wet bulb reading?
50% relative humidity is pretty high, 50 degrees wet bulb humidity...well i can't find a chart of what that equates to, percentage-wise, so I'm trying to clarify.

Then what should be the humidity? between 40-50?

There are quite a few factors to consider, check out this article, it may help you settle on a number.

Thanks for this chart. The numbers, is that how big the air cell should be based on the days the eggs have been in the incubator? I know my eggs have a good size air cell (they just entered lock-down today) I hope their air cells are sufficient for them to hatch because I didn't actually check the size of the air cell.
