Thanks to the -20 temps, both of my males have swollen combs and wattles. The comb is enlarged and oozing a yellow liquid. No discoloration of the wattles except for they are cold and severely swollen. The wattles are round and engorged to the point they are adding weight to the bottom jaw. The males are approximately 3 years old. All males that were untreated with Vaseline have lost 2/3 of their combs and half of their wattle structure to black frostbite. Do I need to dub the come and wattles onthe males thT are showing this engorgement or leave them and see what happens? I am uploading photos now. If this is gangrene, how long can I wait before dubbing? How does one dub a fully mature cockbird?
