What is wrong with my chicken's head?

[Keylime]

I have a flock of 17, multiple breeds. I went away on vacation for two weeks (my neighbor was looking after them), and I found one of my cream leg bars in a pretty bad state. Lethargic, eye black and so crusted over I thought it had gotten pecked out, one wing drooping, and hard, dry, crusty patches all over a bald head.

Is this scaly face, pox, or fungus? She is about two years old and is the lowest on the pecking order, so her feathers never really look great, unfortunately. I checked her for lice and mites and couldn't find any. I gave her an Epsom salt bath, tried to get her eye open (without success), and applied olive oil and triple antibiotic ointment to her head.

What do you think?

To me it looks like she is being seriously abused and feather pecked/plucked by the rest of the flock. I do not think it is a disease situation. I would apply antibiotic ointment to her eye and scalped areas.

You are right. On further inspection, she has puncture wounds and a broken wing. We are also missing another chicken. Our niece came over and l collected eggs without our permission and left the nest box open. Our chicken sitter said she saw a girl collecting the eggs. Sitter came in and closed the nest box. I think a predator injured this chicken and took the other.
