I hatched 3 batches last summer in a home made still air incubator and had to hand turn all the eggs. I'm going to buy an egg turner this year though because unless you have the time to schedule 3-4 turns a day it's difficult to maintain. It just so happened that I was out of work and was available to do it but even if you do work just turn them before you leave in the morning, when you get home and before you go to bed. In my bator I had a piece of 12" plywood with 1" round notches to set the egg in. I marked an X on one side and an O on the other, keeping the blunt end pointed up I tilted the egg from X to O and vice versa every time I turned. No need to pick them up, just move em a little but you need to do it as quick as possible to avoid losing heat and humidity. I managed to do 24 in about a minute.
You really need to set them in something to keep them stable or you're going to have a hard time putting them in the right position. If you candle, just be careful handling them. That's when eggs get broken and it's heart breaking when they're actually developing. Good luck, experience will teach you more than anyone's advice.
