Today my chickens got soaked and the have a dry coop to roost in out of the wind, but I checked them just at dark on the roost and one hen especially is still very wet. It's been getting down in the 30's and 40's F. at night. Do I need to turn the heat on in the coop with a brooder light? I would rather not turn a light on them just yet. I'm wanting to give them a couple weeks to take a break from laying. Do chickens get hypothermia? Thanks in advance for thoughts and suggestions!
