My roo, Cuddles, is not enjoying his first winter in the frigid temps (-15) of Northern Wisconsin. Despite slathering his adornments with vaseline, he has what I would presume to be frostbite. My birds drink from a 5 gallon bucket with horizontal nipples, so he hasn't been dunking them in the water. I have ventilation in my coop, but am now questioning the adequacy of it. My other roo is a black australorp, and only the tips of his comb have gone black. I have moved him to our basement in an extra large parrot cage and provided food and water. I have not handled his swollen bits because they seem quite tender. How long will it take for the swelling to come down so he can return to his ladies outside? Is there anything else I need to do for him in the meantime? This is my first flock, and first winter, so be gentle on me!
