Ive often heard that vasiline is a great protector against frostbite on larger combs and gills, and used it many cold nights on my Silkie Roos....but now im hearing theyre also cons..... and i just rubbed down my large combed leghorn hens. tonight it will be three degrees. point being; my question is, what is your experience with vasiline on combs/gills? have you heard of or experienced any said cons? thanks for reading and/or responding
