Hello! A juvenile barn swallow was found on the ground at a horse farm. It was trying to fly up onto a concrete area, but couldn't because the concrete area was too high (only about 2 inches). Upon investigation, the bird's wings were injured, with the flight feathers on the halves of the wings closest to the body, missing (the shafts were present). The outer feathers were fine. How do we help the bird? Will it be able to be fed insects and worms? (I know they primarily eat insects.)
