This is an encouraging answer. It makes sense, after all wild birds find a way to stay dry in even the most violent storms. I didn't want to assume that chickens could, since they're domesticated animals that aren't native to these environments. We have a high percentage of evergreen trees here, which should offer plenty of shelter. One potential issue is that, from my understanding, the most sheltered part of a conifer is up against the trunk. However, it behooves chickens to roost on thin, faraway branches that won't support the weight of a raccoon. Of course, I could put metal flashing around the trunks of trees they roost in, but that would remove those trees as potential habitat for squirrels and other climbing animals, which I'd like to avoid if possible. I hope any chickens that decide to roost in trees can find a good balance and stay safe
