I had a light braham. Maybe 3 years old. I saw no signs of illness. No standing around looking miserable. Ate the treats and looked good. Free ranged yesterday and was on her roost at bedtime. Found her dead this morning. Her comb was very dark. It was sopping wet under her. Her backside was clean, so the liquid came out of her mouth. Just want to make sure I don't have to worry about the other hens. Any idea/help would be appreciated.
