Hi, I too am in Australia and have just joined, I have been a chook person for a few years but now have four ducks who should start laying any time now. I started out looking for Indian Runners but could not locate any nearby so I have a pair of silver appleyards - George and Mildred and a pair of Rouens, Fred and Ginger, they are absolutely beautiful. I am still keen to add a couple of runners to my happy group and have found a lady on the other side of town who will have ducklings anytime now. Do you think it will be o.k. to add young ones with the adults or would you keep them separate for a while. They would probably be four weeks old when I get them and the weather has just turned very chilly here. From another Aussie quacker.
