What are your outside temps? I think to be on the safe side I'd set up a brooder, you may have to bring the goslings in and keep them inside till the weather settles down, they will probably have them outside and if they get wet and chilled you'll lose them, sometimes first time mamas don't always do a real good job in keeping the babies warm. Have you candled the eggs since she started?Well we r.down to the last few days. Ms millie has stuck with it this whole time. Since its been so cold I take hot tea several times a.day. this is a pitcher of hot water. She has 7 eggs. Praying we get some babies. Can here no peeping yet. 29 days.....excited
