I give mine mazuri waterfowl in the morning when I let them out. and they free range all day.. then more mazuri in the evening when I put them up.. plus they get a salad in their water.. Daisy and Stanley are in one night pen and Judy is in another by herself.. the salad may be just chopped romaine, or may also have other veggies cut up into tiny pieces ( cucumber, zucchinni, tomato, celery tops, chopped carrot scrappings, beet greens, black eyed pea leaves). oh last year they enjoyed sweet potato leaves. Fruits I give every so often ( cut up grapes, straw berries , tops to, cantalope, and watermelon) not too often on the fruits as the sugar isnt good for them
They also like to eat the bird food that drops from the bird feeder.. Hubby didn't know that my can of oat groats had DE in it and dumped it into the can that had wild bird food ( grrrrrr) he though it was dust.. Now theres oat groats going to waste on the ground cause the wild birds aren't eating it.. I placed bucket under feeder to hopefully catch some of it.. the ducks can't eat it all that quick..
I have mixed lettuce planted in garden also some rugula, beets, and radishes. So So far the ducks haven't noticed it yet.. fingers crossed that they get some size on them so we can eat it too..
this past garden season they loved to jump in the raised bed and nibble on the beet tops.. and forage in the leaves that covered the potatoes..
they get corn in winter with their mazuri.. to help keep them warm.. they also love Iams cat food.. original formula
