Strange egg

[TheDenaChickens]

Hello, one of my older hens layed a soft shell egg today that had no yolk but had a white egg shaped thing in it was this an egg in an egg? It Didn’t have a shell just kind of jelly like and why no yolk? Just wondering if cause for concern or just because she’s getting older? Thanks

I think it's a white yolk. Let me look for an article written about that.

If you scroll down near the bottom there's a section on yolks. How's your hen acting? Does she seem normal?
