Resuced a hen, how to help her?

[ilovemychickens2]

Hey guys! My mom got a Facebook message asking if one of our chickens were loose, because there was a lone hen in a tree (it had just started getting dark) It wasn't one of ours but we knew nobody else had chickens in the area so she was far from home, shes terrified out of her mind and probably traumatized as I had to slowly creep up on her to catch her, her tail feathers were all messed up and it looks like she has fowl pox on her comb. I'm taking off from school tomorrow to stay and care for her, but what can I do to get her comfortable and start feeling safe?

Dark and quiet will help, like a laundry room.
That may be a cockerel.
Please do not put it anywhere near your birds for atleast a month to make sure it's not carrying a disease. rake care of your birds first and then that chicken
