We live in Vancouver, WA. Have a Runner duck female that has been laying on a nest, today the ducklgs are making their appearance into the world. They are not in a coop, she made the nest in the middle of a shrub, the weather during the day is about 50 degrees and night approx 43 degrees. We are unsure of what are actions should be to protect and keep the ducklings warm. She has about 17 eggs to go, we know that all may not make it but we want to do what we can..Please tell us what are next steps are.. Thank you, greatly appreciate all input.
