Twin duckling egg.

Oh, that's really interesting. Do you have a pic from another angle? That's a rare little specimen, I'd hang onto that. Or give it to a friend who likes weird animal specimens.

They are going to a friend who likes to collect odd things. They have 2 heads, 4 wings, 2 tails, 1 body and 2 feet

Unfortunate for them, but really cool. Too bad there's no realistic way to put them in some kind of CT machine and see what the skeleton looks like.

Great job on the eggtopsy and pics!

I'm always curious on how far they developed and what might have happened. This was a complete surprise

It was well worth investigating...don't think I've ever heard of twins from a single yolk.
Was rather skeptical when you said you saw 2 heart beats...am really glad I kept following along. I too am insatiably curious about biology, and most other things.
Will your friend preserve them in formaldehyde or...???

It's in an airtight canister with 65% isopropyl alcohol

This wasnt the original twin duckling. This was a second that I only saw 1 heart and 1 embryo
