I'm also thinking this chicken looks like a young male. Very thick legs and uneven coloring on the longest wing feathers. Also lack of ear lobes so that indicates it's young. If it is male, people unfortunately abandon them, or they get out as they try to roost on a fence. It does not look like a meat bird to me right now, but if it is, it's considered humane at the point they get too big to comfortably walk to slaughter.
If it is a female, because the comb is a full color, it would be laying an egg soon once it has been fed for a bit longer (think five days).
There are many considerations one should take before diving in to chickens, which include having the smallest flock being 4 female hens, a bachelor flock being only males but could be a challenge, and a full flock being 10-14 hens to one male. Additionally, when ordering a coop, there should be around 2 sq feet per bird in the coop. I've seen many online coops that are ridiculously tiny (marketed for one or two birds) and wouldn't be appropriate for someone's feathered friend in the long term.
If it ends up unreasonable to keep this chicken, craigslist is a place you could legally list the chicken up for adoption/sale and hopefully find it a good home.
