Black swirl in the egg?

Sometimes blood can get into the egg and this is what it may have been.Of course, it's impossible to say without seeing it.

Thanks Joyful.

Very unlikely to be a worm as we worm them regularly and they were done a couple of weeks ago.

After speaking to her recently I think it is likely to be a blood spot or meat spot. She did say that the colour looked like dark blood rather than the black she said at first. She said the egg didn't smell bad.

It worried me at first as she said it was black. But on reflection she is in her eighties and her sight may be a little off.

I told her to put any peculiar specimens in a pot and ring me next time so I can see it for myself.

I was worried at first and now I am just intrigued.
