If a nest is full of eggs (I’d say more than 6 – although zebra finches can_x000D_
successfully hatch 7 or 8 chicks in a clutch), I would recommend discarding the eggs._x000D_
Chances are that none of the eggs will get enough heat to develop fully. If you have more_x000D_
zebra finches, you could of course always redistribute the eggs among the different nests,_x000D_
but I would only recommend that to someone breeding for a specific purpose (other than_x000D_
just seeing how the chicks develop).
