Optimal egg tilt?

[Roward74023]

Hello all. I am building a cabinet incubator, and more or less using a block on one side of an egg tray to tilt it, then switching the block to the other side of the tray to tilt it the other way (repeat each time it's time to turn).

What I'm trying to determine is the "optimal" egg tilt angle. What angle do auto turners stop at and start the other way? It looks like maybe a 45° angle ish?

Thank you!

Hello, I haven’t ever used a cabinet incubator, but I did read that yes, the optimum is 45 degrees. Even 5 degrees can impact hatching rate. I will have to find the source, but it was somewhere reputable like an ag university or something!
