Weird new rigid texture on eggs recently

[chickenreyna]

From two different healthy hens, too. Not fresh starters or old hens neither. Not near as smooth as usual. Any ideas?

Age, diet, stress, infection are a few things that can change egg shell texture.

Can you post pics please? It could be either an excess amount of calcium, or a lack of..

Most likely just random calcium build up, nothing unhealthy just an oddity that occurs every once in a while. Although I could be wrong pics would be helpful.
