I gave two of my female runner ducks to someone with Khaki Campbels. They needed more females and I needed a drake, so I ordered one and gave the two away. A day later I figured out that I gave them my favorite black female, so I asked if I could get it back and give them another one. When they brought it back its feathers were all gone on the back of its neck. It made me so sad. Is that normal when you introduce new ducks??? I hate to give them the other one if it is going to get beat up by their ducks - I'm not much of a farm girl, so am I being too protective. My ducks don't pick on each other. It made me want to cry.
