Its the right thing you did, Sherrie, by not feeding them when its getting colder. Their metabolism slows down during that time, and even though they might beg for food, their body does not digest it all that much, and it can rot inside them, or rot in your pond and take a toll on your water parameters like ammonia/nitrite/nitrate, especially since during that weather the good bio bugs are not that *active* either.
I was at a koi/goldfish show yesterday, and none of the fish there (over 150) had been fed at all or only minimal amounts during the last month or so. And when asked why there was still poop in the tanks, it was explained with the fact that the fish ate the algae off the walls of the pond, and that was their only food. A lot of fish experienced pond owners don't feed their fish at all once temperature hits 60 or 55. It gives the fish a chance to clean itself out, as well as absorb any unlayed eggs in females.
So, my advice would be - keep doing what you are doing! Your fancies seem to be happy with you!

Do you have a filter with your pond?
BTW, I moved your post into the pond section, so there will be even more helpful people with lots of advice there, as well as a general *Preparing your pond for the winter* on top of the pond section!
