I agree with the advice given by CluckNDoodle on resetting the hatch days. On my second use of the 360, I manually rolled the days back and didn't realize the turner wasn't working until like day 11. You need to hold down the buttons for 5 seconds and reset the whole timer to make the turner...
I hatched 15 out of 22 shipped eggs in the Nurture Right 360 from Tractor Supply. It was my first time and I just followed the directions. It has a known issue with the fan screen but mine came with the modified part installed. It is discussed in a thread here on backyard chickens.
