We have two young male goats with horns. One is a gentle nubian and the other is a dominant and feisty nigeria dwarf. We'd like to add another animal to our barn, but we don't want to run into problems with having to separate animals (the goats have free run of the barn and share one large pen). We have the opportunity to adopt a bottle-fed lamb--but I have heard that polled sheep do not do well with horned goats. And I have heard the same about mini horses as well. Are we just limited to another horned goat or poultry really? Thanks!
