One of my hens is laying what looks like wrinkly eggs.... The shells are fully formed but they're wrinkled. Is she ok? Here's some pics of the worst egg I've gotten so far, just out of the coop today.

Wow...I just went and collected the eggs and one was wrinkled just like that. Never happened before. Wonder what caused it? :/

Corrugated Eggs
These eggs are characterised by a very
rough and corrugated surface. These
are thought to be produced when
there is an inability to control and
terminate plumping.
Causes:
• Inherited
• Newcastle disease or infectious
bronchitis
• Excessive use of antibiotics
• Excess calcium consumption
• Copper deficiency

Wrinkled Eggs
Wrinkled eggs have thinly creased and
wrinkled surfaces.
Causes:
• Stress
• Disease e.g. Infectious brochitis
• Defective shell gland
• Over-crowding
 
One of my girls laid very large double pulled eggs when she first started laying. Now all her eggs are average size but most are wrinkling. I think she doesn't have the greatest control of her muscles were the eggs form.
