I have just read the story about missing chicken eggs....
My son has 3 chicks and noticed recently that some were missing.As his chickens do sometimes wander alongside the back of some houses, he went and had a look...one of his neighbour had prepared, just outside his back fence, a nice little nest.....when he told me, I suggested that when he next saw some eggs there, that he take them and put in their place a couple of hard-boiled eggs.....the nest has since disappeared.....my son does not eat all the eggs he gets and does give some to any neighbour who asks him.....
