I have six hens and only one has started laying. They are all about 21 weeks old. The first layer (which was this past Friday) gave quite a nice long egg song right after she layed. Since then, she has been quiet. You'd never know that she just layed an egg unless you go and check now. Is this common? Will she sing again or is she just of the mind, "Been there done that."? My neighbors are probably pretty happy :>)
The egg song is an individual hens choice. Some sing at loudly every time, others just quietly do their business. Yours may sing again, or not.
