A cockerel normally becomes sexually active at around 24-26 weeks. He's pretty clumsy at first, but he keeps trying. It would almost unthinkable for an 11 week old cockerel to be sexual active or functional.
Perhaps I was unclear, my BCM Roo mounted one of my white rock hens; So I'm wondering if perhaps my Rocks are older than 11-12 weeks.
I bought them from a gal who bought them from a breeder & then got in over her head.
Thank you for the tips & info.
