If you've never been to Wisconsin during winter, it's pretty cold. Starting to be 10F - 20F everyday. I did a good amount of research before I even had my chickens, and learned about the 'magic' of Vaseline! I don't know where/how to apply it, I just researched it is good to prevent frostbite/help heal it. I haven't tried doing anything yet because I don't want to do something wrong and hurt them! And like the title says this is my first winter so I'm trying to keep all of chickens alive, and of course the weather was not a surprise because I've lived in Wisconsin my whole life! Any help would be great! Nobody has frostbite yet but I'm always one that likes to be prepared!! Thanks in advance!
