Last week I adopted two 5 month old Rouen drakes from a gentleman looking to reduce his flock. This is my first experience with ducks so I'm a little unsure about some things. The previous owner told me that he fed them Nutrena All Flock once a day so, to avoid changing their food, I went and bought a bag. Their first full day I gave them about 2 cups of feed and they inhaled it, but ever since then the fellas barely touch their food. I do give them peas or romaine lettuce every evening and they eat that just fine. It's been pretty hot lately could that have something to do with it? I'm concerned that they're not getting the nutrition that they need.
