I was, or am really, in the same boat as PJQuail...I have been turning my eggs whenever I go check the incubator for temp., etc..
An article I found here stated that some have found a more successful hatch rate when they frequently turned the eggs through day 7 and then they slowed that rate down to 'normal'. I leave eggs partially slanted in their carton pockets overnight ( for me that equals about 4-6 hours ). Then I both slant the carton and/or rotate the eggs throughout the day. I also decided that, wise or not, as I am completely new to this, to leave a very lightly dampened sponge in with eggs to bump up humidity, and then remove it first thing in the morning. I figured out my hygrometer is garbage, so while I wait to replace it I will stay on the conservative side with humidity... until I can confidently start the candling process.
I am too inexperienced at this to offer exacting advise other than research, research, research!
The one thing regarding attempting the Dry Hatch method is to keep in mind...you have to have good humidity in the ambient surroundings for this to be effective ( that's the problem I am running into now. ) any other summer we 'd be bathing in it and of course, not this summer...hence overnight sponge!
Look forward to hearing others stories as I am fretting much over these little guys and keep hoping/working towards the best.
