Love the way they run creches for each other. Sensible ducks. Though of course, sinister too... ;)
These belong all to that single mother. THere are 2 r 3 other sets running around too that are smaller and when the ducklings get near each other the mothers get mad and chase them away quite viciously.
Yes very well behaved. They only broke up their tight little group cause I moved closer to them to get a good picture.
