it probably doesnt really matter -a hen doesnt know what degree she turns, but she is continually moving them
dunno, my last hatch was 87% hatch rate on their sides, turned 3x a day 180*
I'm leaning towards hand turning on their sides. I'm just too worried the string that holds the rack up could snap and then BAM a buncha scrambled eggs is all I have. Also, I'll have heat sink rocks so hopefully opening the lid won't change much. Thanks for the input!
