What age do Buff Orpington roosters begin to mate or crow?

[Foristers]

For Buff Orpington owners - 2 questions (that may have the same answer??)
1) At what age do BO roosters start to successfully mate?
2) At what age do BO roosters start to crow?

Thank you in advance.!

Most roosters start to crow at two months.
