AD,
Can you see the eggs well enough to gauge size (use a comparative, pin head, rice grain, snow pea ...) Also, can you count the number of eggs (100, 500, 1000). These are good clues as to whether or not you have a chance at raising some of the young. Generally speaking, the larger the egg and the fewer the number, the greater the chances of success. If they are fertile, and you can see them, you should start to see changes and little eyes develop (regardless of size or number). If you have a camera, photograph the eggs at least once a week and enlarge the pictures on the computer (then post them for the rest of us to enjoy).
