hole in egg

[garyinaudrain]

I have one hen that lays an egg with a hole in the small end of the shell. The hole is about the size of a # 2 lead. What is the problem?

Does she do this everyday? That is odd. Even when chickens peck at it they leave a larger hole than that.

I'm sure someone will come along who knows about this problem. And,

In the first few weeks that my Buff started laying she laid an egg with a bigger whole on one side, now the eggs are fine but her eggs still have a problem with cracked shells (not all the way thru, the membrane is intact)
