Chicken and Goose Eggs

The other day David and I were out walking and we found an abandon goose egg. Of course I had to bring it home. If it hadn't been ice cold, I would have tried to hatch it. I did take pictures of it sitting next to a large chicken egg - quite a difference. David is going to drill holes on the ends of it so I can drain out the yolk and keep it. Someone told us that it has a goose egg has a green yolk, so I'm very curious to see.
