It was remarkable to me, when upon first releasing the peafowl into CCH, what they chose to eat. They did nibble on queen anne's lace, but were really drawn to the burdock plants. Although burdock holds most of its value in the root, the peafowl could not stay away from eating it's leaves. The one larger plant I had within g CCH soon got stripped of its leaves, and then they started reaching through the fence to get at the other plants there. After coming out of a long period of being penned, it would indicate to me that burdock should be used in my winter tonic when greens are scarce. It makes sense because burdock is such a deeply nourishing and a restorative herb.
