Incubation turning???

Hello all, bad news on the first attempt at hatching I had 24 eggs with zero hatch, 😢 however I'm learning everyday! I believe it was an old batch of eggs someone sold me plus I have learnt the seasons have a say on the eggs! This time the incubator has been set up and running and temp is set and humidity fine! Enough of the rambling.....

My question is I have a Brinsea Eco with a added "cradle/rocker" which means my incubator rotates, about 1 cycle every 2/3 hours, I know this maybe a daft question but do I need to rotate the eggs around? What's best way to do this? Or is this actually doing the work? I'm just trying to eradicate any thing I may have done wrong?

Thanks for any advice....
