Have to possibly do huge water change of 2,000 gallons. Help?

We might need to drain 2/3 of our pond to see if there are any dead fish or frogs down there. I hate to do this, but I'm getting concerned as we don't see several fish. Additionally, I'm concerned about the following:

* Ducks may have bnrought parasites? Fish are flashing at the surface once every hour (we have about 40 fish in 3,000 gallons).

* Many fish are missing some top and rear fin structure. I can't tell if it's fin rot or has been torn from rambunctous ducks and scraping on lily tables.

* A few fish are super lethargic. But our water is still not quite up to 60 degrees yet.

How can I do such a huge water change without shicking the fish too bad? We don't have a way to hold water to age it (I don't think), and we do add de-chlorinator and stress-coat stuff. Thanks for any advice you may have!
