my first incubator was a turn x 7, never hatched a thing. then I bought an avey incubator (no brainer- turns automaticly, adds humity automaticly and lets me know when there is a power failure) holds only 24 eggs, no more. very pricey butjust what I needed to get me started and not worry about zero hatches. then I bought a chickubator- holds 3 eggs, uses a lightbulb, $20, and finally bit the bullet and bought the big one that holds, what 100?eggs. I use them all but the turn x which I sold just depends on what I'm doing
