Abnormal Egg, Hen Won't Come Out of Coop

[mondaymonkey]

Our RIR, about a year old, just layed this weird egg. She's being very noisy and won't come out of the coop into the run. She's not in her nesting box, she just won't come outside. Anyone had a similar experience?

That lump/egg looks like it might be what they call a lash or lash egg, Sometimes they come with an egg, sometimes they are just "laid" alone. They seem to think it is part of the lining of the hens reproductive system, often seems to happen with hens that are internal laying also. It may or may not be a problem if that is what it is, some hens seem to be fine, with other ones it means they are near the end of their laying cycle. Old BYC thread on them and some links with other pics.
