Hi there. And welcome to BYC.
I have so many questions!
Yes. Please do post more photos. They tell so much.
A droopy comb can hint of lots of things.
Dehydration and poor conditioning is just one.
Being sick is another.
The others may be keeping her away from food and water. Do you just have 1 feeding station?
What do you feed them? (Looking for a protein percentage here)
Roosting on the couch at night, out in the open will certainly doom her to being picked off by a predator, and soon, so we have to figure this situation out.
How does her weight feel?
Normal or “light” for her size?
Is her keel bone sticking out?
How many birds roost together in how big of a space?
The edge of her wattle in the pic looks a bit like a touch of frostbite that’s healing but that may also be where someone grabbed her and pinched. Do you live somewhere cold?
The other areas look more like peck marks, but possibly not.
Chickens can be ruthless and can inflict horrible damage, even kill each other.
She’s seems docile in the photo.
Could you look inside her mouth for me and tell me if you see any sores or chunks of yellowish plaque anywhere inside her mouth or lips?
And you are sure that no one else in the flock has sores on these areas?
There is a contagious virus called fowl pox usually in warm weather or warm weather climates. It can exhibit as sores or ulcer-like oozy lesions around the head, face, eyes, and in/ around the beak and mouth.
There are two types wet and dry.
I’ll attach some reading about that at the bottom of my post.
Looking forward to your responses....
