The disappearance of the chick.

I know it's silly to be upset over a chick, but he isn't in his nest and I can't see him anywhere. I can hear little tweetering noises, but can't see the chick anywhere. I will get Rob to have a look when he gets home. He doesn't look old enough to be trying his wings yet. Oh dear, letting go of ones fledgling is hard isn't it. (I keep looking at the nest, as though the chick is going to miraculously appear again).
