I have a 19-week old speckled sussex who has been laying for less than a week (4 eggs total). For the last two eggs she's been hanging out in the nest box after she finished laying and leaving only when I shoo her out. Both times I saw her starting the process and came back to collect the egg over an hour later (I got distracted) and she was still there! Is it possible she's already gone broody before her eggs have even normalized?? This is my first time raising chickens and I definitely didn't expect this in all my reading!
