I feed the layer formula to my Anconas and really like the pelleted form since ducks can't clean up spills as well as chickens. It's a little more expensive than what I fed my chickens (Fleet Farm's Sprout layer feed), but it's not overly expensive, and to be able to get it in a pelleted form is worth it for the small flock I have. They seem to do well on it.
One funny thing I have experienced with this feed is that normally I purchase it from Mills Fleet Farm, but I once bought it from TSC and for some reason the recipe must have been a little different (I don't know if it was a fluke or whether it was actually mixed by a different supplier, even though the two stores are only a mile apart) - it smelled a little more molasses-y and it made their poop STINK! It was quite odd. I almost threw the bag away, but I ended up just suffering through it. When I went back to the Fleet Farm version it was just fine again. I don't know if it was just a weird batch, but if you do run into that issue but still want to try the feed, try another store.
