I have three ducks that I am keeping with the 9 chickens and one peahen I got altogether. They get along great. Their pen is adjacent to my chicken run and until now, they all have gotten along fine. Today, I noticed one of my hens and one of the new hens sparing through the fence. They were really going at it. I stood back and watched, knowing they couldn't hurt each other and I wanted to see what would happen. One of my ducks got all up in their business and started chastising them. She got in between them and just chewed them out in duck language. She went after the hen in her pen first and quacked and quacked at her until she moved away. Then, she went after the hen in the main run and would not stop chewing her out until the hen backed down. It was too funny and I'm so proud of that duck. Anyone else have a duck that likes to keep the peace?
