Candling question

[Hsinichung]

I heard from a friend that on day 20, I should hear chirping sounds, is that true? Also should I candling the egg during this time to see if it is still alive?

On day 20, you should hear peeping. And eggs should be in lockdown for the last 3 days so I would put them back and leave them for now.
