Do most people do water changes in Winter? I've been doing them but
less often.

Same. Depends on the weather. Always good to check your WQ before doing a
water change, to make sure there is no ammonia showing. If the fresh water
going in has a higher pH than the pond, it would make the ammonia more
toxic.

As far moving the fish, I agree with Ingrid.

I also agree with checking the pH before moving them and try to slowly
change the QT (within 0.5 pH) before moving them. ~ jan
