I have 2 little miniature jacks. I recently had to isolate them because they were starting to become aggressive toward my goats. If like to put them in our cow pasture but I'm not sure how they will do with our bull. They have been kept with the cows before and did fine and our bull is generally very gentle. We do not want to help them yet because we are getting a Jenny soon and was hoping to breed one of them with her. I'm just nervous about putting them in with the bull. Has anyone ever kept a mini Jack with a bull before?
