I have 3 lovely girls, all different breeds (Danish breeds, as I live in Denmark), and they have been very good at keeping themselves busy. We make sure they always have food, that are healthy for them, and lots of water to drink, so they can have at it whenever they want. But lately we have been getting lots of complaining from them they can sometimes "scream" for what seems like hours (a bit exaggerated due to stress caused by having neighbors living close up against us, and we don't like being a pain to them). We have no idea what is causing this, they have a lot of room to roam in, they have each other's company, they always have food and fresh water. Could they be bored? If so, how do I keep them entertained, without being out there with them constantly? I hope someone has knowledge about this, as I just want my girls to be happy! Side note: they are 7 months plus some days old, and are all laying, 5-6 days a week. Edit: they are roaming, pecking grass while they are "screaming", not hiding from anything that might have scared them.
