Swirled psycadelic egg yolks?

[Animalian]

The other day my mum boiled some of my 3yr old RIR's eggs and when we cut them in half, the yolks were all swirly, the colours were yolk colour, but light yellow and her normal orange yolk colour swirled together.

Mum didn't trust them and fed them to the dogs. The RIR is the only one laying at the moment, my 1yr old mutt is being broody on nothing (she may sit on my RIR's daily egg for a few hours) and my plymouth rock is busy raising her two chicks and hasn't started up again yet.

I do not have a rooster.

Just wondering what would cause this, her feed hasn't changed lately other than them getting shell grit now...I have pics and will post if need be later.

I would like to see a pic of what your talking about. BTW - how are the dogs feeling?

they're fine and happy. I date my eggs as i collect them so I knew they weren't old. Nor did they smell bad.

Wish you had a photo of them. I have no idea what could cause that. Good luck - hopefully someone else will know.

sorry it took so long, their eggs are back to normal now. But here they are.

lol I shouldn't say it, but that is super weird. Do you have a rooster? Maybe early embryo development?

Weird, for sure. Do you have a rooster? The reason I ask is that within the first two days of incubation of an egg, the yolk takes on a swirly storm cloud look, before you see an actual embryo. If you don't have any chance of a fertile egg that has developed for a couple of days before boiling, I have no idea.

Nope no rooster, she hasn't seen a rooster since she was 6 weeks old lol

Then, I'm stumped. Wish I knew!
