If you can check the eggs while she is off the nest, you may get a better idea of what's happening. If the eggs stink or are oozing, you may as well get rid of them before they explode. If they seem good, you can afford to be patient. Did you candle? Otherwise, I suggest that you double-check the length of incubation for Crested Orp duck eggs - and Crested Peking, because who knows which side of the family is dominant for hatching times. Give her a few days after that and then remove the eggs. Be sure to listen for tapping and peeping before tossing them, in case they are just late. I have never had ducks but I have geese. I know that often if the gander is a yearling that the eggs may not be fertile, even though he may take care of "his part of the deal". We experienced this with our Pilgrim gander this year... but hope for better things next year. Good luck! And don't forget to post an update telling us how things turn out.

I think he was telling her to get back in the nestbox! LOL! The male here feeds the female whether she wants it or not. Sometimes he just pecks her and pecks her to make her take what he is trying to feed her. LOL! Mine are on their second nesting...Dad is busy feeding fledglings now while mom is laying eggs. Donna

Papa will sometimes stay in the box but he will not incubate them. Bluebirds can sneak in and out during the incubation phase so I wouldn't be surprised if they were there and you didn't know it, especially if the box is not in an area you see often.

I really hope you don't "pick" off the male bluebird. How long are you waiting to see if the bb eggs hatch?? I have not heard of that many eggs not hatching.
