You can tell by their color as hatchlings. the big silver one i posted a picture of in my last post was hatched with a beige colored head & tail & it's now growing in it's silver & white 'hard feathers', it'll be a Silver Pied as an adult.
(blue fawns & lilacs have a sometimes very slight difference in the darkness/richness of the color.)
I will give you a couple examples:
Solid White Duckling(notice the solid yellow fluff). A white baby should have a pink beak:
Silver Duckling (has beige-colored markings). A Silver baby will usually have a blu-ish tint to the beak/legs:
So would a beige/fawn duckling look the same as the silver, and do you by any chance have a front pic of that duckling?
ETA: Would a beige duckling have tinted legs and beak or no?
YAY!
Here are Ming-Ming (in the front) (yes, she was named by 3 year olds.) and Integra (in the back.) Any idea what color these little girls will be? They were sold as "red", but.
