They've started making noise when I poke at the nest – a sort of hiccuping – and they make squirmy lunges that heave the fuzzy nest cover. The photos were taken just a few seconds apart, but you can see they've launched themselves into different positions. And their faces are becoming more rabbity and less piggy. (Except for the black one who has a fat head.) I think there are three whites, one black with a white chin, a chocolate one, and one grey with orange highlights. Wonder what colors they'll be tomorrow?
