Hi. I decided to try incubating eggs for the first time with my preschool class. I got a Rite Farm Product #1200 for my class. The instructions are limited. I really want my eggs to hatch. I know you put them pointy side down but I'm unclear on whether I need to turn my eggs in this. It says"universal egg turner" but for the life of me I can't figure out how it turns. I've had it on for a week and never seen the trays move. If I do it by hand how to I move the eggs if they are pointy side down? Any help or advice is greatly needed!
