Found this on my 18ish week old hen this morning. One wattle is swollen with a large black area on the tip of it. The other has a small black spot on the tip. She did not have this last night at bedtime. Looks burned almost or like frost bite. I'm in southeast Georgia, but it's hot and humid here, so no frostbite. It's bothering her you can tell, but otherwise she seems fine. Hasn't been sick, is eating and drinking fine, active. Breaking my heart, she's one of my favorites.
