I have a large 3-sided shed that is divided in half for the goats and the horse. Right now the mini is in his stall during the day and let out at night. The goats are on the opposite schedule.. out during the day and in their stall at night. I'd like to let them all out at the same time but this *smart* mini has gotten over/under/broken everything I've put up to keep him out of the goats' side. The goats need free access to their side while keeping the mini out of their alfalfa pellets and minerals, plus need an escape from him if they so choose. I first tried a chain snaked through an old hose and this worked for a while until he figured out that he could get in by going backwards under it. He got in but couldn't get out. I lowered it, but my big doe had trouble getting under it. I then tried a 2X4 but again, low enough so he couldn't get under or over it, the doe had trouble getting under. I need some new ideas so he isn't doomed to stay in the stall everyday!
