Hello, my african goose has been sitting on some of her eggs for a while now and when I candled the eggs (its probabily been 26days?) some are pitch black inside and the others have an air bubble but it have the lines that look greenish color. There are 2 eggs that have live babies in them one is a goose and the other is a duck or chicken, the one goose egg is only at day 4 when shes been sitting on it for more than that many days. Also, if these dont hatch will I be able to put other eggs under her? She never gets off of them, I have to put a bowl with her food in it next to her.
