Despite my euphoria last year when the ducks took a dip in the pond, they didn't make it a regular practice. I eventually resigned myself to the fact that they'd never be pond ducks.
It was so dry over the fall that the spring feeding the ditch dried up. Once it started raining, water flowed there again, but the ducks ignored it in favor of their kiddie pool.
At first we just tried driving them into the ditch. "Hey, remember this? You loved it last year!" Even though their feet were wet, I guess they were too scared to realize where they were.
We applied weed-eating and subtle pressure. We moved their food closer and closer to the ditch. Then one day they remembered, or maybe just rediscovered, how much they liked it there.
You've heard that phrase about water and a duck's back...?
One day last spring we saw them wandering towards the far side of the pond. "What in the world are they doing over there?" we wondered, but didn't think much about it. That night they came back to the pen with one less duck in tow... So we're down to seven ducks now. They may forget the ditch, but so far they've never forgotten that there are coyotes beyond the yard.
