Nah, they see me pick the eggs up and then drop them so they go splatI've heard the same, I'm not sure how often it causes egg eating. Personally, my girls have never been able to peck the eggs open, and they really don't bother unless I crack it first. But perhaps chicken beaks are better at it.
To play it safe, I believe the trick is to crush the shells so that it isn't too similar to a whole egg. Cooking would be even safer to really differentiate the eggs in the nest, to the ones in the bowl.
