Hen layed egg with no shell

[a123andpoof]

I was watching my BR hen and she looked like she was trying to lay well she layed a egg with a broken membrane and yoke. The yoke fell and was instantly devoured the membrane just kind of stuck to her should i be worried? First time I have seen this.

I've had this happen to me a number of times and they always seem to pull out of it after a day or two. I wouldn't be worried unless the problem persists for a week or more.
