Ducks and eleven-year-old boys have this in common. They both hate to go to bed on time. Chickens are relatively easy. When they arrive in the white van in their little cardboard boxes you keep them in the henhouse for a couple of days. It registers that this is their home. When evening comes they begin to get a little spooked and look nervously to the right and the left. Then one of them wanders in and then another. Finally the final chicken realizes she's all alone and goes 'squawk' and runs in quickly.
Ducks are another matter. We've built a nice little ramp for the duck house but do the ducks go in at night - even with a plate of food inside? Do they hell! We've been chasing indignant ducks every night this week. One hopes they'll get the idea eventually.
