Mine do. When we first moved here we had poision oak or ivy or both everywhere. Huge 2-3 inch diameter vines growing up our trees. The goats eat it like candy. You have to be careful if you're alergic though. Cause they'll have it all over their coats and if you pet them you'll get it. Hehe
Do you mean she has the blistery rash? I've never seen a goat with the rash but I've seen white goats get black spots on their fur from it...it just wears off....Maybe a shampoo in an oatmeal based soap like aveeno would help her but as far as getting rid of the rash, I guess it would be like us getting it, takes awhile to dry up and heal.
