pullet with no egg song

[hansolo]

We adopted a red star when she was as about 5.5 months old and laying. She laid normal for 3-4 days and announced her eggs, then for maybe 2 weeks either no eggs, shell less or thin shelled eggs. She's been laying normally and consistently again now for a few weeks but she never makes any egg songs anymore.
Does anyone have laying hens that do not announce their eggs?

Other than that she seems quite happy readily jump on people's laps.

Mine never do, and they lay every day

to tell you the truth out of all of mine I only have one that sings an egg song.

Mine haven't started an egg song. Of course, They've only laid their first eggs.
