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. Old BYC thread on them and some links with other pics.
