I received eight beautiful khaki campbell ducklings by mail order yesterday. Seven of them have slightly darker feathers and bills, while the eighth is lighter colored and has a slightly pinkish bill (when compared to the others). Is this information applicable in sexing the ducklings or is the lighter colored one just a duckling who decided to express his/her individuality? I can give a hearty "thumbs up" to healthychicksandmore.com for sending wonderful ducklings and chicks to us. I will definitely use them in the future. Thanks!
