A female kestrel (who we named Kessie) eats an eggshell from one of her hatchlings while sitting on them and incubating the rest of the eggs. We watched her eat this shell and others via a webcam installed in the nesting box. We had never heard about Kestrels eating their eggshells so this was surprising to see. More pictures of the kestrels are @tkestrels on Twitter.
