I "had" a grey little duck...she was sitting on 12 eggs. She was there this morning....I went to town, came home, she is gone. I waited for 3 hours, she never came back. So I fired up the old bator. What temp and humidity do I hatch Duck eggs??? With her being gone for over 3 hrs...with they still hatch?? PLEASE pray my little MoMo comes home!! I miss her little fuzzy head. and her hubby, Shadow...has been walking all over the property, looking for her as well.
