Help !! I think they are duds

[calcat45]

Ok so I tried hatching my first batch of eggs but so many things have gone wrong. They sat out almost 10 days and then when adding water for humidity the lid got left cracked and temp dropped almost 10 degrees.
I am on day 22 and nothing no peeping no cracks. At what point do I assume that they are not going to hatch?
Thank you!!

The lower temperature probably slowed down their development a bit. Give them 'till day 24 or 25. Fingers crossed!
