Twins? Two heads? Something else?

[squirrelgirl01]

Hello all! I previously posted my first adventure with incubating some eggs from my cousin's farm here. He asked me to incubate and hatch some more for him, actually, so I've been doing that with a new (hopefully properly functional this time!) incubator. However, I've run into something... interesting.

Last night, Day 7, I was candling all the eggs for the first time to check for development. I came across an egg that is seriously confusing. It very distinctly has two heads and two eyes, I KNOW I'm not crazy here! But everything I saw online said that a twin egg would be two yolks, two sacs, two separated babies. These babies are stuck together... almost like they're conjoined? Can anyone tell me what in the world is going on here? They were moving so as of last night I know they're alive.

Someone else had a similar oddity.

@WVduckchick just had a similar egg, I believe. Actually I believe her egg was a little different

I have no answers but I find it super interesting!

I've had eggs like this. I figured out it's an eye, & tail nub.

I just had one quit at day 9, yours appears to already be a quitter
On day 8, mine was fine, but the next day it had stopped growing.
First pic is around day 6

One time I attempted to hatch twins. They quit on day 10.
