I wouldn't necessarily have to wait a long while. It all depends on when he drops(which, he already has) and even then he may not act studly. I'm aware he can, and will, but there's no telling when. Training and working with a stud colt is more dangerous, and more tedious, but it is something I'm aware of and prepared for. Not all stallions are raging maniacs. My colt's sire is an absolute doll and loves attention. He was kept next to another stallion with only round pen fencing separating them, and they could care less. I'm hoping Henny has that same laid-back disposition.
