This is my first winter with chickens and from reading previous posts I kind of get the causes and how to treat it but I still have a few questions. I learned that the main cause of frostbite is not proper ventilation and I'm pretty sure that is my problem. The roof to our coop is not completely connected to the walls so that is a little part of the ventilation but we don't have any windows and I think that is my problem. So, until I fix that next spring does anyone know what I can do to help prevent it? I have been putting Neosporin on, maybe twice a day, but it keeps getting worst. It is for my leghorn hen. Thank you!
