All of the sudden my girls seem to be clucking LOUD and OFTEN! They have plenty of food and water as well as clean boxes and coop. It seems like they are yelling at me! Do you have any idea what they are clicking about? The only thing I have changed recently is that I have added some scratch to their lay crumbles, where as they have only had lay crumbles for a long time. Whether or not that is right, I don't know, so tell me if it isn't!
