Seems as a small child I can remember my father going out in the fall of the year and picking Sumac berries to feed to the chickens. Has anyone else heard of this being done? We have these trees growing against the edge of our property down by a creek. In the fall and winter when all else is dormant and bare you can see red berries growing from the trees. The bright red berries look rather beautiful against a white snow background. I've watched wild birds land and feed on the berries. I do not plan on feeding them to my flock. Just curious if anyone else has heard of this. Smooth sumac (Rhus glabra) It grows to a height of about 10 feet. It bears alternately arranged leaves with serrated edges, which change to a crimson hue when fall approaches. Smooth sumac produces small green clusters of flowers in spring, which later in the year give way to bright-red berries that last all through the colder months.
