We have a 1 year old Khaki female duck that has all of a sudden become very broody. She made a nest, collected her eggs in it and for 1 week has been sitting on them. I have two questions: 1. To successfully hatch, how much time does a duck actually have to spend on the nest in the 28 days or so of gestation? (she leaves the nest only occasionally, maybe just once a day) 2. Will we need to provide food and water right next to the nest? Thanks!
