Thank you! I was thing she was a Snowy but looking on line the drakes all looked the same. How could you tell?
You'll need to test breed her to see if she is heter- or homozygous for Snowy though... I see the bottom section of her speculum is washed out, not blue, but they will wash out completely when they eclipse so could be that.... or she could have hidden genes in her...
As for the drake, like WV said the head color is the most distinct difference between pastel and blue fawn... pastel has a steel grey head like yours and lighter body as well... blue fawn has a dark charcoal head like my boy here, and a darker body overall as well...
A butter drake looks similar to pastel drake, except the claret bib extends from the front at the sides down the flanks... and they also tend to have washed out eyestripes visible...
