Rough surface eggs

[Spartan22]

Id been getting this rough almost calcium deposits on the outside of couple of eggs lately. Just wondering what they are and what causes them. Those could actually hurt the chicken vents right? Are they getting way to much calcium?

That's fairly normal and not really a problem. Check out the egg quality handbook top se what they say about it.
