Hi, I am just wondering how long a mallard hen would leave her nest during the incubation period? One decided to use the side of our house for her nest and laid 11 eggs. I believe the incubation period began, because she only left her nest once a day and would return. This Friday she was there in the morning and we haven't seen her since, it's now Sunday(so bout 2 days). We have been goin' out our garage and avoiding her area she laid in. We can see her nest under my bush from our sidelights, so we can watch her progress(little kids are excited). We have neighbors that have grandkids that will go on our lawn and haven't told the kids about the nest, so they won't bother her. Just hoping she comes back and not sure what to do. Thanks for any info
