Thank you for sharing, these posts are so helpful. April 15 my husband brought home three two day old chicks, one BO, one Ameraucana, one RIR. We love them, they are a lot of fun. The BO ended up being the alpha hen, pecking the others when gathering around treats, she was also our first layer. She started laying September 19 after displaying very strong PMS symptoms, our sweet little Ameraucana followed her example on October 1. By now all three are singing loudly but our RIR has still not started laying.
If I am correct the song is supposed to distract potential predators from stealing eggs. It seems that our girls now finally sing after laying an egg or if they think somebody else is laying. But maybe they sometimes just like to practice?
I wonder how long our RIR will start laying?
