Developed embryo in egg laid today?

[slowloris]

This is the weirdest thing I've ever seen. First the background. I had a flock of 14 hens (no roosters). On March 18 I picked up five Isa Brown pullets from Family Farm and Home. They were supposed to be point of lay but hadn't started laying. Early this week I got a couple of small "beginner" eggs. Well, today I found a broken egg with what looks like a developed embryo inside. I know the pullets had been in with roosters, so that's not the question. The weirdness is that this embryo must have developed to this point inside the hen. (Laid in a spot that I check multiple times a day). It was actually in the box with one of my established hens but it seems completely impossible that it was hers.

Any ideas?

That looks like a lash egg not an embryo.

Even though it was inside an egg with white and yolk?

Yes, that can happen.

It's a lash egg.

The chickens all seem healthy and are acting normal. What should I watch for?

Feel belly's, from below vent to down between legs, for swelling.
Might feel like a water balloon.
