Has anyone ever have a runaway chicken establish to live next to them?

A runaway chicken has decided to move in to our garage and although we chase him out he is determined to sway around and live with us. I don't know what to do. There are no farms anywhere in verbs but he is very tame and not afraid of people. I enjoy no idea where he came from and I asked around and not a soul in my neighborhood is missing a chicken. Should I keep him? he seem hungry. If you think I should keep him please tell me what they put away and everything bc I have never had to look after a chicken before.
Which ferret litter is best?
Answers:    Just consent to him stay he obviously has decdied you are his family. Are you certain it is a he (rooster) and not a she (hen)?
Chickens eat chicken scratch which is a mix of grains for chcikens or crumbles. I nurture both and mix them in equal parts for my flock. make sure he/she have water to drink also. If it is a hen you may even get an egg 3 or 4 times a week.
