Cayuga Feeding plan

[Spring Fleet Chickens]

So we have a small flock of Cayugas, they are our breeder birds and I have been feeding Kalmbachs Duck & Goose. They seemed to do well on it till I switch over to the 20% Full Plume (for chickens in molt) and they have thrived on it. However I do wonder if I should change it back to a more specific waterfowl feed. We can get Nutrina as well and Ive been thinking about trying their duck feed. I have a pair of show quality Cayugas coming in this weekend and this is what she feeds her flock. So I've been debating on getting that for mine as well. It seems to run about the same price as Kalmbachs waterfowl feed. The only thing I don't like is I can see the full ingredient list on the Nutrina. I know I like the Kalmbach feed, but at the same time if there is better out there I'd like to try it.
SO my two questions are 1)who feeds what and why? 2)any other SOP breeders out there wish to shed some light on the best feed for their breeder/show flocks?
Thanks everyone!
