Cheryl is right GELD him. Stallions are not anything to take lightly or play around with and he will be alot easier and happier as a gelding. Learning all you can is GREAT. But good horse trainers are born that way. They understand behaviors/instincts/actions-reactions. You should really try to get him the best start possible. Don't know your age but is there a local trainer that would be willing to apprentice you or a summer job. Take what you learn there don't be afraid to ask questions and apply that to your gelding at home. That way you have someone to speak with. The book will say to do this and the horse will do that. Don't know about you, but my horses can't read and sometimes come up with an answer only they will understand. What then.
