Rescued Dove part 1

This young dove was chased by other birds, and hit the window where i work. It couldn't stand one one of the legs, so i tok it home to safety and gave it water and wild bird seeds, after 4 days, it started to stand on both legs, and now after 6 days, it has been out flying and are standing fine on both legs. I have the dove in a rabbits cage, and today i left the door open for several hours, but the dove seems to like the safety of the cage.
