How long after eggs start rocking? UPDATE: They're hatching!

[chik love]

I have some eggs in the incubator and I havent heard rockin or seen pipping yet. it is day 20.... I hope they will hatch! I candled the lighter shelled eggs and I could see veins. but the other day I went to check on the incubator ( I normally check about 5 times or more a day) And the temp was at 104F.. IDK how long it was at that. some-one please give me advice! Thank you!

questions
When do they start to hatch?
Should the have started to pip yet?

Ugh! I'm so excited my babies are rocking but no pips yet I think I'm so anxious to see them that I keep hearing phantom chirps. But we still have 2 days left to go till hatching day.
