    I've read about some HUGE roosters here, and am wondering at what age roosters are as big as they're gonna get. My Bianco is RIR/Brahma, both of which are biggish breeds--how big/heavy is he likely to end up, and at what age?

    Thanks!

    Quote:At what age they have their full growth depends on the individual breed. Some breeds are slower to mature than others. I think by 6 or 7 months a RIR would have his full size, but I think Brahmas are slower to grow, so it may take your guy a bit longer than that.

    My Thor, a dark brahma, continued to grow and put on weight until he was nearly two years old. He weighed 13 lbs. in his prime. A LF brahma is not considered full grown until they reach two. DH and I were outside watching "chicken TV" yesterday evening and both noted how big my brahma hens are now. They are 3 1/2 years old, just finishing up a molt, and are absolutely huge. The largest hen weighs 9 lbs.
