Wrinkled Egg!

My hens started laying last month. Since then I've gotten a few leathery eggs and some very small eggs. This wrinkled egg is maybe the weirdest so far.

That is often an indicator of a bout with infectious bronchitis. Sometimes, when they molt, they produce some off eggs, and there can be other causes like a new layer, but that wrinkled paper bag look usually means IB.

Here is a good pdf article on abnormal eggs:
