I've had hens for two years. Got a nice little coop and a small run. Birds free range during the day. My neighbor loved the look and with no thought, went out and bought himself a dozen hens. He's down to two. He makes no effort to feed, so with his permission (I'd have done it anyway), I started providing for his girls. The problem: His girls roost high in a tree in his yard. This is their first winter. I didn't worry too much, I live in Texas, after all, but the last two nights it's gotten down in the teens. The bigger problem: I just had a hysterectomy last week and I can't go after the birds. Could they possibly survive this without getting frostbite? I'd make my neighbor climb up and get them but he's not home. Is it worth tracking someone down to climb a ladder into that tree? There are no leaves on the tree, i.e. no protection for the girls. Appreciate your advice, opinion, etc.
