That sounds really scary! maybe you can get some of those little solar powered yard lights. they just went on sale here.
It was really scary. When I first found her in the nest I started talking to her, telling her it was time to go robed for the night. Since the Africans are more skittish, my approach should have had her up and moving. When she didn't I got worried. The geese never gave an alarm call, so I knew a dog hadn't gotten in the yard, but I thought maybe the very mean, big tomcat or worse a raccoon had gotten her while she was laying. When I touched her and she didn't move, and there were no signs of struggle or any blood, I thought maybe she had died from internal laying, even though she was very young. So I grabbed the flash light to check everything before I disturbed her body even more. The light is what made her move and wake up. Thank goodness. And a yard light won't work where they prefer laying, it's nestled between 2 buildings. But I will figure something out, I do not want to have another near heart attack like that again!
