Double yolk duck egg in my bator & yolks look ruptured or something??!!!!

[bellah1]

I set 18 duck eggs 3 days ago & didn't even pay attention to the yolks. I chandeled them tonight & the humongous one has two yolks! But as I looked closer and it looks like there is a lil bubble on the end of each yolk almost as if they have ruptured slightly & the leaked out yolk is suspended attached to the rest of the yolk. Has anyone heard of this? Or could they be misshaped

Wow. That is really interesting! I'm hoping someone with more knowledge chimes in because I'm curious what will happen with that egg!
