Tracy, if you decide to build a brood pond, get with me, TJ, highflyer, or Snrub. Lot's of ideas that would really ease the movement and maintenance on a brood pond.
I did keep a feeder on this pond for 2 years, and may still add another one at some point. But, small ponds like these can really kludge up if too much food gets wasted. In my particular case, I lightly dye this pond to cut down clarity and help control algae, and my fish won't eat for a couple of day while they adjust. Even 2 or 3 days of uneaten food is not a good thing on a pond this size.
