A friend found a young chicken outside his building that must have escaped from one of the butcher shops in the Italian Market (where he lives). I am rescuing it as it definitely won't survive the night (predators). I currently have two New Hampshire Reds that are about 4 years old. Can someone please advise me as to what I should do or expect? I was planning on just adding her to the coop, but she is definitely young (maybe a few months) and I know nothing about her. Feeling nervous but don't want her to die.
