My duck went broody, built a nice little nest while we were gone and didn't get her eggs up. She is an Indian runner. She seemed broody, not getting up off her nest. So i ordered some fertilized eggs and we pulled half of hers. She had 8 in her nest. 2 days later our fertilized eggs showed up and we put them under her and took her others. She is still rarely getting up off the nest, but layed an egg last night. There are no other ducks or chickens, so it for sure is hers. Is she technically brooding if she's laying, should i start counting down the 28 days yet to hatching?
