Thanks for all the replies and reassurances!
The "pieces of cooked hamburger meat" is closest, but this is way weirder than anything on Kathy's funky egg page! Here's a photo:

It almost looks like placenta.
No more weird eggs or any laying...
One of our three hens laid something very strange yesterday. No shell at all, it was just a smear of yolk and egg white, coating a chunk of flesh that is about walnut-sized, with a smaller chunk (raisin sized), as well. The big piece kind of looks like a gizzard??? We have never had any...
Looking to adopt or buy 2 or 3 hens asap to be companion to our companion Aracauna hen, Sara. We recently lost our other hen, Sophia, and are looking for friends for her asap. Prefer tamer chickens. Breed, age, race, religion not important. No roosters, please. We're in Madison.
