I have three female Chinese weeder geese about 2yrs mother and 1 yr daughters the gander was killed by a dog last summer. The 3 females have been laying eggs since February and one mounts the other two but all are female. About two weeks ago they start sitting on eggs in two separate nests. I put 4 week old chicks in a wire cage on the grass today and the geese stayed by them. When I walked the 3 month old puppy by the cage she tried to get them. The geese went after the puppy and I had to pull them off her. Usually the puppy runs at the geese and they run away. The geese were definitely protecting the chicks. I am wondering if they would mother them. The geese go in the barn at night so maybe they would take the chicks. Has anyone seen this behavior before?
