Not everyone handles duck ratios the same.
Ducks form bonds and form territories. These bonds change throughout the mating season. Your number of drakes and hens may or it may not work fine. Adding more hens could make it better or it may not. Personally I try to keep my duck hens to drakes...
I put feeder ports in a large garbage can. I can put 150 pounds of food in it. I use multiple 5 gallon buckets with nipple waters. With the waters I would not want to rely on just one. This set up is designed for an occasional vacation. I still have someone look in on the birds each day.
