Please tell me what is going on! We found this egg near one of our nest boxes. It appears to be a white egg inside of half a brown egg. We have only brown egg layers. The white shell is totally hard and solid, just like a healthy normal egg. Then half the egg has an additional fully formed brown layer. The brown layer looks like it was broken off, but I don't see how that could have happened without breaking the white layer. There is nothing between the two egg layers - no membrane or air space or anything. Also, I broke the hole in the egg to see how hard the white prt was - it was not broken when we found it, it was a complete whole hard egg, and the inside was totally normal. We do have one chicken who has mysteriously been laying soft eggs for a couple months despite having free choice calcium and none of the other hens having any issues, but I have no idea if the two are related or not. We don't know which hen layed this egg - we have red sex links and rhode island reds plus a plymouth barred rock rooster.
