I have no idea what happened but it made me think of something
I can remember from years ago that we talked about fake eggs. Someone found a site where you could order fake eggs (and they were real expensive) from a lot of different kind of birds. We were talking about who would buy a fake egg. The person from the fake egg site discovered that we used his site and he sent us a post, this is what he wrote, as far as I can remember :
There are a lot of people who are collecting real eggs, my fake eggs looks so real that these egg collectors are the persons who order eggs on my site from birds they don't have.
And one other point: there are birds who like to steal eggs from other birds, it's easy to fly in an empty nestbox and steal an egg.
Do you remember that we had a disappeared egg 2 or 3 years ago? We had camera's but we didn't found what happened with that egg
