Incubating eggs HELPPP

[chickenobsessed]

I made an incubator out of a old cabinet. I have a computer fan that is 6V, it is directly above half of the egg turner so that it would blow the heat down to the bottom, the fan is about 6-12 inches from the eggs, but the half of the eggs that has the fan blowing on, there is no duck in them but the ones that don't have the fan blowing on them have eggs in them Could the fan be effecting the eggs or is it just those eggs aren't fertile???????? Thanks

The fan could be to powerful, kind of like a strong breeze on a hot day may still seam cold. So the eggs may seem cold and not be developing. This is just a thought

How could I resolve that problem? I have to keep the fan in there to get the heat to go to the bottom

If that is the problem, maybe moving the fan up higher or to a different location in the incubator.
