Previously I've limited myself strictly to hens, so Roosters is a fairly new experience for me. This Spring I will be getting a few types of birds as Straight Run (mainly birds that will be for meat). As an advocate of slow-food, I'm avoiding the Cornish cross meat varieties. I plan on keeping some of the stock for breeding. So here is the question, when will young males start become sexually active (or, when will they start fighting with other males)? At what age will this occur? The only Roosters I'd had previously were given to me full grown. I've never had more than one Roo before, and certainly never raised them from day-olds. Any help would be appreciated.
