it sounds like they are laying an egg. Nothing has scared them. I will walk outside and one is doing it in the coop.Whew! At 13 weeks? That's pretty early... none of mine did egg songs until after they laid.
They did do alarm calling prior to egg laying, which sounds very similar, but they had a big scare when a tree fell on the coop roof.
