Hi, welcome to the forum! Glad you joined!
The first time you turn the light out they may peep for 10 to 15 minutes, then they typically go to sleep. The second time they might peep for 5 minutes, if at all. After that they typically just go to sleep. Each chick has its own personality so you may see some differences but this is pretty typical.
At some point they will need to learn. You can teach them now or put it off.
I have not read this old thread but I'll address the peeping. Chickens can have problems with change. Going from daylight to dark can be a big change if they have never been through it. It is pretty common for them to get excited the first time. But chickens are also adaptable. They pretty soon get used to a change.I'll see tomorrow night whether they'll need the light again or they're feeling safe in their new home?
