>>I've been told Ball eggs are very durable and not to worry about stuff like that, but try not to let it happen. Look at it this way, if you don't know which side is up, how would anyone else be able to tell you which way to turn them??? I wouldn't worry. It's in the hands of the gods like always.
Actually..There is a way to tell which way is up..Well in my opinion anyway.
Candle them and if there is a side with a yellow glow to it.Then that is the side you want on the bottom.
I'm of the opinion that the yolk adheres to the inside wall early on.Which dictates their needed placement.
I also think that this is especially prevalent with eggs from late laying females..As it may be possible that the internal adherance begins before they are laid.(Which could explain how some eggs go bad mid incubation.Even though they were fertile.)
The next question is "why do some good eggs go bad at all?"...Well,perhaps the yolk actually crushes down on the yet to be fully formed baby.Causing developmental issues,etc.
If i'm wrong then i'm wrong...BUT,so far every rollout i have gotten has hatched and lived..As well as several that i have removed from the stuck together cluthes and inverted as i saw fit.
As a matter of fact i just did this yesterday with a ten egg clutch(with one infertile)that had three rollouts and three that needed to be removed/unstuck and set upright.
