Hello,
@Bjoern: I thought the same,but now i think,that hardshelled eggs can be moved.I talked to other gecko keepers about this,and they said,that after a time(maybe 2 weeks after laying),the eggs can be moved or rolled.I don´t know,if this is right,but in this species(H.angulatus)i never had any problems with the eggs,that rolled out of the cork tube.They all hatched.
If i get PMG-eggs,i try not to move the eggs,but it happened,that a PMG-double clutch rolled by accident after moving the clutch out of the sanseveria,and both eggs hatched.
I try not to move the eggs,but i made the experience,that a rolled egg can hatch.
I think,softshelled eggs like Underwoodisaurus milii should not be rolled,they are quite different to hardshelled eggs,experienced geckokeepers told me.I have no experience in this,i have only a milii pair,who breeds.
I tried the best with my schoolenglish

Matthias
