after using the eggs for wizard promotion are they of any use? Can`t sell them.

I'm not very far into the game, but I haven't been able to find a customer for the eggs in either Valeia or Ishad N'Ha. You can sell the nectar, though, if you're inclined to do so. Doesn't seem to be worth it to travel all the way back to the temple, unless you're on the 10 serapin quest perhaps.
