[hoppyone]

13 eggs in the incubator an a couple are changing shape they have been in there for 3 weeks now, temp constantly at 30-31 humidity 70 -80percent, am i doing something wrong, lost one not fertile but had a white fungus on it so it was removed looked like it split thought to much moisture?? :cry:

How are they changing shape?
Do you mean they are becoming plump in appearance?

Yes swelling in the center

Eggs grow in size as the embryo develops, my lizard eggs almost double in girth
