How do you tell if a duck egg is fertilized? Is it the same as chickens? I have three ducks and was told one of them is a drake, but "it" has no drake feather. I am getting two eggs a day, like clockwork. They lay early in the morning, before sunrise. I know who the two hens are, the question is if the third is a drake. I can crack an egg open to see if it's been fertilized and that would answer the question. So, how do I tell? The duck in question has a different quack than the known girls. Is that a sign? Why is there no drake feather, then? Thanks!
