most turners make one cycle in 4 hours or from far right to far left in 2 hours.
one thing to keep in mind with manual turning versus automatic turning: many automatic turners never stop turning, they operate slower than you can see by the naked eye. in an extremely dry environment the embryo could still stick, and turning more often is needed. when you turn by hand you are making the movements faster, the embryo excersizes more and moves farther. its typically better to have the faster turning motion. many modern turners only turn a total of 60 degrees, or 30 degrees right and 30 degrees left of center.
Petersime, a commercial incubator company experimented with a 180 degree turning radius (90 degrees each way from center) and had higher hatch rates - as advertised by them. i can see how the 180 degree turning would be benifical for waterfowl, as most of them do better when hatched on their sides - but im far from the expert in waterfowl.
and to familypendragon: i know you've gotten tons of advice, and most of it is good advice in normal situations. everyone has different hatching methods they have learned from experimentation with their incubators. my 2 cents on hatching shipped eggs for my sportsman incubators: when i put shipped eggs in for the first 24 hours i let them set with the large end up. after 24 hours i do one full cycle turn and return them to the "upright position" i do this one time a day for the first 3 days. after the 3 days i let the automatic turner take over. ive had 100% hatches and ive had 0% hatches, since i started doing it this way i typically have 50% or greater hatches. i cant tell you if this is good or bad advice, its just what works for me.
