So I’m curious, I purchased 5 ducklings online from a hatchery. That was in August. Assuming they are all females, I didn’t pay much attention to their appearances. Recently, I noticed on my two blue swedish ducks a little green dot on its head, like what a mallard would have. I got to looking and one has a curled tail. They both sound like my male Pekins! Sure enough they are males! Just wondering if it’s normal when ordering for there to be mistakes.
