I don't have enough experience or information to answer your question, Mitzi, but I do know that most animal behavior results from an interaction between genetics and environment (nature vs. nurture). If you were to castrate a 2-year-old aggressive ram, in all likelihood the testosterone in his system will have already "hard-wired" his aggressive behavior. But if I were in your shoes, I'd want to keep my options open for as long as possible. Therefore, I would not castrate the bottle rams unless their behavior got bad enough to justify it. I'd breed them for as long as possible. Also, those ram lambs could be fertile as young as 4 months; certainly by 6 months.

Carol, if a ram were neutered at that age after that sort of testosterone related behavior had begun, would the behavior stop?
Or is it a learned behavior that becomes a habit? (In your opinion)....I had thought the testosterone mediated behavior started at a very young age. If it takes several *years before the "ram behavior" starts I'd dearly love to leave one of them intact just long enough to breed 1 or 2 of my girls.
