Yes! It's just an incubator that turns them while on their side. That is a good perspective, I didn't even think about it that way! That makes me feel better.
I have eggs on day 7 in their incubation cycle. I unexpectedly am getting more eggs that need to be incubated but they will not fit in the other incubator I have. Would it be okay to move eggs on day 7 from laying on their side, to an upright incubator? Or should I figure something else out...
