Learning to quack

This morning we put the ducklings in the new pen round the pond - they were so happy dabbling in the mud, diving under water and having a general good clean, flicking water over their backs and waggling their stubby little wings and tails. I also put them in the polytunnel for a while where they happily searched for worms and slugs.  They are getting more used to us, they sit quietly on their bit of grass in the bathroom instead of running off - it does make you feel like you are being talked about though as they start contact calling as soon as we are out of sight. They also like to run up and down the long landing and into the office when we are working and come and sit near our feet. Just now one has been trying to quack, it was very subdued and sounded a bit damp and also made the other duckling look confused.
