Brahma take at least a year, I think at least 18 months to get to full size if they're from good lines. Also, those large dog sized roosters are almost always a lie and just clever angling for the camera
Yeah, I know that about brahma. The very last thing for me is the bird being a good table bird, so I don't care if it takes too long. And I've seen that trick with brahma before, it's very dumb in my eyes. Reminds me of the wannabee macho men who get a bully breed just because they want to look tough, but it ends up being too much dog for them
