can you tell if fertile straight away?

i know after a week or two you see the pinkness and sometimes can see veins but can you tell as soon as they are laid if they are fertile or not? iv got 3 eggs laid so far (waiting on the 4th) all laid today, they have yellow colour when candled with a pink circle with a dot in the middle.....is that a good sign or do you really have to wait a few weeks to find out lol

Sounds fertile to me.

The pink circle you are discribing is the Bullseye. Here are some pics for you.

Fertile eggs usually firm up to a leathery consistency where infertile eggs are thin-shelled and limp like a water balloon. The bullseye may be visible right away, or it could take a few days to show up. If you are having problems with your eggs molding, you may have the incubation medium too wet.
