It does need to be around others, but this chick no longer has a mother; even its mother will not mother it. It does not have an established place in the pecking order, so you're going to need to integrate it into the flock.
Typically that looks like a chick with food and water in a wire dog kennel, that has been placed inside the coop for all of the other birds to come see and hear. Its living condition should remain as such until the chick is six to nine weeks old or for a couple of weeks, whichever is more time in the crate.
During this crate time, prepare the coop & run area for its eventual release into the flock by adding ways for the chick to run and hide to get out of the sight and reach of any birds that are overly aggressive to the little one. Place both food and water into one such hidey hole so that the chick cannot be denied access to groceries. You should supervise during this time when the chick is out with the rest of your birds for a couple of days and place the bird back in the crate when you are not supervising (only until you're sure the chick will integrate), and back in the crate at bedtime for at least a couple days. You expect to see some gentle head bopping from each of the members of the flock, or even a back or bum peck. That is the established bird telling the squirt that it has seniority and is normal and important for establishing a healthy pecking order. If the pecking order ritual becomes intense, put the baby back in the crate for a few more days and try again. Repeat as often as needed to integrate.
