@Sonya9,
I put Vaseline on last night, but will switch to neosporin tonight. I also bought some whole corn. Thank you so much for the input! We added two more vents today, fingers crossed....
All,
My fears about our coop design were confirmed when my ladies contracted frostbite the night before last. We bought and installed a roof vent immediately, but this morning, their combs looked worse. I'll start a separate thread about the coop design, but right now I urgently need to know...
