Hi Guys

We live in Edenvale That east of Johannesburg.
We have a pair od Yellow bill ducks spending lots of time
in our unused swiming pool.
They Have sent the night in and around the pool.
and a few days.
What could i do to try get the ducks to stay
Can i feed the water with anything ?
What kind of nests do they use?
Hope to hear from u soon
Graeme
