strange looking egg

[codechicken-2]

I got a strange looking egg the other day the outside was solid but it looked like a wrinkled up paper bag. any ideas?

It could be a calcium deficiency. It could also be a hen just trying to figure out how to work things for the first time. Oyster shells are good for calcium.

How old is the chicken which layed it if you know which one that layed it that is!

its about 1 year old, they do get oyster shell. it has layed one other egg that looked like this one only not as many wrinkles and the other eggs it layes all look fine.
