What is this?? I found in the nesting box today. I'm hoping it's not a lash egg, but if it is what do I do? I have a flock of just 5 layers, and have no idea which one it may have come from. It was the size of a golf ball with tons of veins on the exterior, I didn't touch it with my hand but it felt rubbery when I broke it open, and then just had a yolk and blood clot inside.
