anyone done this before?

[shemy]

what i usualy do is once they have hatched go in and shine the light through each one of them, if its hollow i leave them in and if it isnt i take them out because the liquid has gon solid. tthe mother doesnt know that the egg is hard so therefore carries on trying to hatch that egg, if you take the eggs out that are hard inside they will lay some more, its worth doing hehe
