[Abe the veiled]

Hiya, my female cham layed 61 eggs about a month ago after been mated with my male, most of them have gone black/brown and started to cave in so im guessing there not fertile, but there are 3 large ones that are still whiteish. Heres a pic of them, let me no what you think Thanks xx

Can anyone help??

Possibly your vermiculite was too wet? They could have been infertile in the first place. Any pics of when they were first laid?

the 3 large ones are definitely fertilized since eggs swell over time if they are fertilized. I agree with Julirs, the vermiculite may be too wet causing the eggs to mold over. What temps are you keeping the eggs at?
