I just bought 3 RIR at 8 weeks old. I've been reading about the egg laying song so I'm concern that they will lay eggs in the late evening or the middle of the night. I have neighbors close by so I'm concern about the loudness of the egg laying song. Also, if they chirp a lot now, does that indicate a talkative hen? I have two that chirps a lot while the third one is mostly quiet. Thanks.
