Last night it seemed that some at least of the seven duck eggs we put in the incubator were about to hatch. We could hear chirping coming from the eggs and a tapping sound, as if the ducklings were trying to peck their way out. There was even a little hole in the shell of two of the eggs where the duckling inside had pecked through. So we went to bed expecting to see hatched ducklings this morning. Alas, there were none.
We checked our books for answers. The eggs are actually due to hatch on Tuesday but is seems the hatching process can start a couple of days before the due date when some ducklings knock a small hole in the shell but otherwise leave the full break out until the final day.
So we await Tuesday and the pitter-patter of tiny little webbed feet.
