Not sure where you are in this conversation, but we were getting 5 chickens for eggs and my 14 year old son talked us into getting 2 female mallards. I was VERY skeptical about getting ducks, but relented and we ended up, thru chance, getting 3 mallards and a Rouen. He has been so responsible with caring for them, and we even had them in the house for 2 months!!! while their house/run was being completed. We have fallen in-love with the ducks......and, yes, we love the chickens as well, but the ducks are something else. We are now thinking about raising ducks, Rouens to start with, and my son wants to show them.
We are building a large enclosure for them in the spring because we live in predator country up in the foothills of the Cascades. I cannot tell you the difference it has made in his attitude and sense of responsibility. Even his 16 year old brother and my husband have gotten into it. We are total city slickers who decided to live in the country, but I can honestly say that these critters have brought a whole new dimension to our lives and we love every quack and grunt and throaty murmur. The ducks and chickens, having been brought up together, hang out together during the day, but have their own houses to sleep in at night. They are a hoot to watch together.
Us parents can be a pain in the butt sometimes about these things, but I whole-heartedly condone raising and caring for critters. It has been GREAT!!!
