    I have heard about the time they start crowing but was unsure if this is a good indicator. I have a young Marans roo that I am wanting to put with my hens so I can get some eggs to incubate but don't want to waste my time till I am reasonably sure he's getting the job done. [​IMG]

    That can't be true, I have four less than three month old roosters that are crowing...they don't even look big enough to reach one of my hens...I guess it depends on the breed because mine are Barred Rock and the others are Cochin/Isabrown mix and they are crowing for the last week now.

    I had a 13 week light brahma roo that was mating with my hens. He was the only roo and the eggs were fertile.

    Good question. I've been wondering the same thing. My BR roo is six months old and has been crowing for a long time. He has started mating with the hens last week(that I know of). That is when they started laying. But I have no idea if he has knocked them up or what.

    My roosters were all hatched april 13th, I put eggs 10 eggs in bator and 9 hatched 2 weeks ago. so they were fertile. If I can figure this out right and take the 3 weeks they were in the bator and 2 weeks the chicks have been hatched is 5 weeks, I think that made them 23-24 weeks. Give or take a week or 2. Hope this helps. I know these roosters are the ones who did the deed cause I have no other roosters.
