Yeah we bought them just from our local feed/poultry centre advertised just as runners. It's our first time with ducks so I didn't really know what to look for bar the research I had done online. There were about 15 other ducks advertised as runners available at the same time when we bought ours - it would be interesting to find out what the others have matured to be!
How easy is it to tell the difference between a young swedish/harlequin and a young runner, they were about six weeks when we got them? I'm guessing they look pretty similar just the runners are much skinnier?
Thank you for the super helpful comment!
