As @aart suggested I find 95% of the time in my situation they’ve always just been opportunistic egg eaters. Either the egg is soft or gets cracked when it is laid. I put sand in my boxes so that no matter what there are not rough surfaces to crack them first.
if she isn’t laying, she may be close to lay, and just really checking out what’s happening in the boxes. I don’t have egg eaters per se, but I have about 20 hens that will ATTACK cracked egg. They don’t go after normal eggs in the boxes, so I just drop cracked ones I find right in the coop for them to eat.
