I understand that the recommended times to turn eggs a full rotation is once every 4-6 hours. That's 2-3 hours per half turn or 4-6 full turns per day. My last calculation I need to make in building my newest incubator is the turning speed and how I want to implement it with my existing materials. Is it better to constantly turn and just change directions every couple of hours or should it activate a 1/2 turn every 2-3 hours and stop and not move again until it's time to 1/2 turn, again? I have a 6V, 1rpm, high torque DC motor that I can do it either way with, or a larger gear/chain motor that will only activate when directed and stop in a short(programmed) amount of time. Also, if it was a constant move and just change directions when reaching each pinnacle, how much variance would I get in hatch rates if it were a little faster or slower turns compared to recommended? I don't believe that turning a little slower or faster would or should make much difference. Though, I'd like to know if anybody has any experience with such variance in turning times. Any thoughts are welcome.
