Hornworm eggs

[Toasty987]

Hello everyone. I received 20 eggs last Friday (the batch was laid last Wednesday) but only 4 of them has hatched. How long should I wait before giving up on them? The eggs are having brown spots on them and some are darker than others. What would you guys do?

I found this thread has not been answered yet so hopefully I can bump it up.

I would wait. It's possible that they will hatch at different times. I think you should ask Spyro; he's an entomologist.
