I know this thread is old but was there any resolution? My hen had a very similar looking growth

I'm posting this for my mom because I've never seen this before.....

When my 10 yo daughter was helping my mom check for eggs today, she noticed one of her Orpington hens had a swollen face and some sort of black growth. There also seems to be some nasal discharge. Mom didn't notice her acting strange this morning, but that just means that all chickens came to eat when fed this morning. Her chickens are used for eggs and meat, they aren't pets.

I don't know what her poo looks like because they checked for eggs before sundown when the herbs are starting to make their way into the coop, but she seemed alert when I sent in to see her. Aside from an obviously painful, swollen face she was acting like any other hen. I guess I'm just looking for advice as to whether this is contagious, treatable, etc. My dad was ready to dispatch her for fear that it might spread to the others, but I thought I'd try here first.
