I have two different kinds of Walnut trees in the pasture that is being fenced right now and the horses are going to go out in. What kind of Walnut trees are toxic to horses? There are two black walnut trees and one english walnut tree in the pasture. Are both kinds toxic? Also, I live in Indiana so all the leaves have fallen off of them because it's fall so would the trees be toxic to the horses at this time of year? What part of the tree is toxic to the horses? Please help me if you can because I'm needing to turn my horses out in that pasture ASAP! Thanks!
Also is it just Red Oak trees that are poisnous or are other types of Oak trees poisnous too?
