I added ten new chicks to my flock this spring and they are just beginning to lay. But all of a sudden all but one of the older girls has stopped laying. I don't see any signs of moulting, that I recognize. Do chickens stop laying due to moulting before they start to lose their feathers? And will they actually lose all of their feathers, or is it gradual and you'll just see a few missing feathers? I'm just dismayed. Just when I expected to see a dozen a day, now I'm getting 1 or 2.
