Has anyone seen this before? What appears to be a double shell-less egg? One of my chickens... I suspect, the Light Sussex, has laid consistently (in the nest box) for about a month then... nothing for four days. Here's what I found... under the perch. Two shell-less eggs (L and R - covered in poop) and a double yolker (? - centre) Close up of the double yolker. The membrane is all in one, connecting the two eggs. After four days and 3 x shell-less eggs, she missed one day then laid a double yolker 79gm! and then an egg per day for the last 2 days. I'm hoping that, being young (28.2 wks), her body is just still working it all out and she will now continue with no problems. She didn't appear to be different in her habits or eating. Poop was normal. It's a mystery. I'd be interested to hear if anyone else has had a similar looking 'joined' shell-less egg.
