Can you please tell me what color are the bills on your female Black Swedish Ducks? I just picked my young one up and see that it's bill is going from Black spots on orange or yellow to a greenish color. On Mallards a lot of times that means drake. Can a female Black Swedish have a green colored bill? Thanks for any info you can give me.What breed are the Monty-Phytons? Just curious and thanks for the information about your Black Swedish. I am sure that is what my one little Call Duck is. If you saw how little he was you would say "No Way" but where there is a will there is a Way. lol
