Yep. I thought maybe they were moulting, but no. Caught one in the act yesterday. I locked her up, put eggs in the boxes, walked out for an hour, and they were gone when I came back. So it's not just one. Going to get golf balls today, and rigging up a darkening flap for the boxes. Any other suggestions? I know it's more than a couple, because they polished off 4 eggs in a short amount of time. I really don't want to cull, but will if I have to. And if I can figure out who's doing it. Any suggestions on catching who the culprits are?
