It is interesting what different opinions everybody has! It makes me wonder, is it the brand, the incubator, or the person?I haven't ever heard that, but I am not a big fan of styrofoam incubators. I've tried a number of them, but they're very finicky and are pretty tough to get to stay steady imo. My Nurture Right 360 is my all time favorite incubator. I have not tried the Incuview, and I'd maybe like to someday, but my NR works fine for big eggs too. I just have to manually turn them because they're too big for the turner. Quail eggs don't tend to work well in the turner though. I had problems with them getting turned pointy end up after a while. But I had 20 quail eggs in there and it's some work to hand turn them, so I just left the turner unplugged, and came downstairs (to the basement, where I keep my incubator) a few times a day to plug in the turner and then watch the turner turn them. There's a button on top that you can push and it will turn them. Then I just fixed any that got turned weird and unplugged the turner again. That way it didn't turn them while I wasn't watching. It worked fine and I got an 100% hath rate with all 20 hatching. I sold some of them and kept my favorites. It works perfectly for chicken eggs and duck eggs, but geese/turkeys/peacocks are too big.
