Lately, my hens have been a bit loud. We cannot hear them from inside the house, but when we go outside they are clucking pretty noisily. Is there a reason that they are clucking? possibly the heat? or is it just how they are?? they haven't really been like this before. they are laying right now and some of the hens seem a little territorial. (ex: pecking at others when laying) i try to always have something different for them to eat like tomotoes or fruit, but is there anything else i can do? All suggestions are welcome.
