So for the first time ever, I have a female mandarin duck sitting on eggs! I am oober excited! However, it seems that she doesn't have a mate Will these ducks sit on infertile eggs? Or will she give up if there is nothing in them? She has been sitting for over a week so I am hopeful. I do know that my broody hens are really good at getting rid of "bad" eggs, so I don't know if ducks are the same?? I have 2 females and 5 males total, one female is definately bonded to a male, but not sure about the one sitting. The bonded female goes in the nest too (esp. at night) and there seems to be a lot of eggs! Could they be sharing a nest? What do I do?? So excited for mandarin babies!!!!
