Have you candled the eggs? You can use a flahlight, preferably something like a mag-lite and a small section of a paper towel roll. Shine it in at the large end. Listen to the eggs too for tapping or peeping.

Duration of incubation can apparently vary from 28 - 31 days, depending on conditions. If something doesn't happen soon, I would be inclined to remove them. If you do you can learn something by cracking the eggs to see whether they were fertile. If this is the first breeding season for your geese the fertility could be low.

I'm no expert. My geese are just a year old. At the moment both are sitting on eggs and I'm keeping my fingers crossed.

Fwindle - Update, please!

Well I put the other 4 eggs in some water, and they floated. So I broke them, and they were not furtile. Momma then started taking care of her baby, and the 2 males follow her around, and don't seem like they are going to harm it.
