This is a very neat experiment. I can’t wait to see the rest!

Great article! I had always assumed the hens we just having a little victory song after they laid, or possibly announcing to the other hens about their accomplishment! This makes much more sense. This also answers why sometimes the hens sing the song, and other times they don’t. Thank you for the information and the great read!

Thank you for reading the article. It's interesting that others have also seen the same behaviour and mentioned this in their comments.
