I have this gorgeous Rhode island hen that I have raised from a chick, but lately something's been bothering me. when I go out to check on my chickens she always has her beak wide open and im not sure if it's the heat or something else. I love in Summerville sc, and lately there have been a string of temps in the mid to high 90s for a few weeks. My family is on a tight budget as it is so all I could afford was to put our old desk fan in the coop to try and keep the air circulating. Is there anything I can do, anything to look out for. they always have fresh clean water every day and their run is mostly shaded by vines and a huge creeping juniper tree.
