egg yolk with a "chunk"?

[chesapeakechickens]

We are still new at this and found something interesting in one of our eggs today. There was a portion of yolk that was thick and kind of congealed. It is pretty good size (maybe 1"x 1"x 1/4" or so) and irregular in shape. Does anyone know why that might happen?

Was it laid today? Do you have a rooster?

No, it was from eggs that are about a week old. We do not have a rooster.

Sorry about the late reply... I've never had lumpy yolks before, so I don't really know. It could be part of the chick-growing apparatus inside a bit enlarged or in the wrong place. If it happens every time the hen might have something wrong with her ovary. But probably nothing to worry about!
