Greetings,

So Kiwi laid a surprise clutch of 6 eggs, 4 of them have hatched already and the 5th chick should be hatching soon. However the 6th egg I know is infertile, I candled it multiple times and even now as the early eggs have hatched this one is still completly clear. (thank god Kiwi has such a mild temperament and doesn't mind me toutching the eggs)

When should the egg be removed? Should I wait until they all finish hatching? Or just remove it now?
I am worried about the dangers it might bring to the hatched chicks.

Thanks in advance.
