I assume they are what's called a wind egg. Around the size of an acorn and has ho yolk inside, just albumen. It that the case?
Usually it's when a small bit of tissue has left the infundibulum or other part of the reproductive tract and then stimulates the production of albumen and subsequently gets a shell put around it.
It can also be at the end of a laying cycle when a hen needs a break.
