We've had our ducks for 5 weeks now and are still unsure of their breed(s). We were so sure the buff/fawn/tan colored duck was an Indian Runner because it's penguin-like stance but as he s/he has matured, seems to have lost it's stance. I also suspect he may be a boy. Rather than quacking, he whistles and it looks like his tail feather is starting to curl. The white duck, is not actually as white as s/he appears to be in the photo but more of a creamy, buttery color(I believe they're both about 7 weeks old). Will her plumage eventually turn white or are there breeds of ducks that are off-white in color. Do you think my buff colored guy could be a Buff Orpington? I read somewhere that the Indian Runner was one of the breeds of ducks William Cook used to create the Buff Orpington, which would explain the occasional penguin stance. Thoughts?
