My runners were marked like the one on the left in the second pic, but they were always pretty upright. By 3 weeks old they had the classic "runner shape". I know that isn't much help, but mine also came from TSC. They were marked as Pekins and the employees said that the box they were shipped in was labeled Khaki Campbells. I will try to get a picture in a while, it has been raining on and off all day and they are so muddy.
Yes! They weren't labeled at all and then we were told they were khaki Campbell's so I'm not sure what they are. Now I'm thinking it's possible they're two different breeds.
Adorable!!! I'm hoping he/she is a runner! Now that I've figured it out I've gotten excited about having some! They seem like fun ducks. I wish they both were! I might just have to get more if I can find any!
