I really don't want to heat the coop, but I am running into a bit of a problem. I have noticed that my hens and roosters are starting to get small black specks of frostbite on their wattles and combs and it has sent me into full panic mode. I have cleaned and disinfected their frostbitten areas and slathered all of their combs and wattles in petroleum jelly to combat the cold. I have also started spot cleaning the coop everyday to try and keep down moisture. Before this I was confident that my chickens would be fine this winter, but this has now made me question my coop and just how warm my chicken are able to keep themselves in it. It is made out of pine and is not insulated, but I did stain it. Here is a link to what it looks like from the website I bought it from. It's only the coop, not the run and there are nesting boxes on both sides not one. http://www.cconly.com/coop__hutches/cc-18_series. Last night and tonight I have put a 100 w infrared heat lamp in there in hopes of taking off some of the chill, but I feel bad for the birds because of the red light. I just don't want them to get frost bite. What should I do?
