Nice pics...and that pool is killer.
And to answer your question, NO!
It is not good luck to have ducks land in your pool, as a matter of fact you better hope this does not go wrong. We had a friend that had couple of ducks land into their pool and it wasn't long before others joined in. It became quite a mess with them shitting in the pool and it was more of a pain to get them to stay away. What ever you do don't feed the ducks!
Good luck
