It should be both parents feeding them actually. We had a couple of robin nests on our balcony over the years and they tag teamed one another. In fact, apparently the father's the one who stays the longest with the nearly grown babies while momma's off on a new nest. We once had the juvenile from the previous nest (somewhere else) showing up at the latest one on our balcony and making an incredible racket. Momma paid it no attention but papa gave it some food.
