Now that you mention it, when I cracked the egg open, the membrane wouldn’t burst. I had to poke it with a butter knife to break the membrane, and then when it was cracked into the bowl, it looked as if it had the potential to be a double-yolker, but if the second yolk had broken into a million...
Went to the nest boxes today and found this. I’ve seen many deformed eggs, but none like this one. Does anyone know why something like this would happen?
