Help for hatching newbies

(Which I am)

I had good succes with my last incubation, and then I had a chick take out the fan kit by bumping it while I was not home. This dropped the temp, messed up the humidity, and killed (shrinkwrapped) many a chick.
So here is my question. I am having a good hatch this time....


1. Hovabator 1588
2. Humidity 55-65% plan to up it for last days
3. part shipped eggs part mine
4. Temp regulated and stable....


So some people I have heard keep their humidity at 55 not 65 and seem to be having trouble....
How many of you keep your humidity at these levels, and are you having success?

Thanks!
