Thanks ! Tell me one more thing that what will happen if humidity is very high like 69,70,75 or 80 for first 18 days.

If the humidity is too high during the whole incubation time, not enough moisture evaporates from the egg. The result is that the airspace is too small at the end and the chick takes up too much area within the egg. This makes it more difficult for them to hatch and in bad cases they will fail to hatch and die in the shell. Other factors like size of shell, age of egg at setting etc can affect whether the hatch is successful also.

Humidity will depend on the surface area of the water, the temperature of the air, the air movement and also the humidity of the air in the outside environment as it enters the unit. The incubator cannot lower the humidity. (Actually, the altitude affects humidity as well but that's not generally a problem for any of us.)

When you first fill a tray, a few parts get wet and as things settle you get an temporary boost in humidity. After a few hours it settles to whatever it's going to be.

If the humidity is still too high with only one tray full, try it without any water added and monitor the result.

The reason we try to control the humidity is so that we can control the amount of moisture that evaporates from the egg as it incubates. If not enough evaporation takes place, the chick doesn't hatch successfully. As long as there is some humidity there and it's close enough to the desirable levels things work out fine. I've hatched at higher humidity levels here due to our climate and it can still be successful as long as it's not too high. In my opinion, the temperature is far more critical than the humidity.

I wish that I had seen this thread before I bought one of these pieces of rubbish. (:-(((

The "automatic" turner seems to be a toy. Turning is by a supposedly synchronous motor, so turning should just be a simple matter of timing. OK, the 2-hour countdown seems to work, but the actual turning is totally haphazard. Occasionally the eggs are turned, but mostly the turner ends up in a random position. I will set some wake-up calls in my local PABX and try to work out what is going on. My first guess is that the "ON" time for the motor is incorrect but there does not seem to be any way to correct this.
