Emily, in another post, you talked about walnut leaves being good for goats. I have several nice big Black Walnut trees and I have heard so many conflicting things about them so I just don't let my goats have any leaves. What can you tell me about this? Also, another person told me that the black walnut shells were a natural wormer....any thoughts? The Black Walnut nuts actually have fallen into the cow trough, were they have turned the water a reddish color and the large animals have drank it with no ill effects. Was I inadvertantly worming them naturally?
