Big White Ducks are Super Sluggish in New Location - WHY??

[DianaTX]

I have a question: A couple of people have brought their ducks to live here at RV Park pond. 1 out of the four is a mallard and the other three (minus the one white one that myteriously disappeared) are big white ducks. For some reason, they are not adapting well. They seem to be moving very sluggishly, having problems moving around and constantly laying down wherever they move to to rest. What's wrong with these guys? Someone said something about the "brackkish" water but I'm not so sure that's a culprit. You got any ideas? I live in the Houston TX outskirts area.

Thanks for any help.

Sent my response to the other thread. Thanks, DianaTX, for being persistent with communicating, and taking care of these ducks as best you can.
