My 2 female ducks are broody and have been sitting together on approx 10 eggs. I'm wondering if after they hatch the ducklings will I need to remove the babies and bring them in the house with a heat lamp or will the mama ducks be able to keep the babies warm enough. Temps are typically 80 high 60 low. Also curious if I need to keep the food separate? Thanks for any input. We are trying to let the mamas do this as naturally as possible.
