I've taught crayfish anatomy to probably 1000+ students over the years, and when they molt they actually reabsorb some of the shell's calcium carbonate. As a result, the new shell following the molt is rather soft. Furthermore, calcium carbonate becomes calcium and carbon dioxide when mixed with acid. I guess the real problem is swallowing the hard object so that it can get into the stomach...
If their is food/energy to be had, evolution always seems to find a way to access it

Thank you very much, Dennis! The lighting conditions were not that good in the morning and I wanted to freeze some if not all the actions, including the water splashes .
