It depends. Typically hatchery birds are smaller and buffs are the smallest variety. Mine personally wasn't from a hatchery and was 11 pounds at 7 months. I never weighed him after, but I assume he was a few pounds more at least, especially since Brahmas grow until they're two years old! Sadly about a month ago Cheeto got his neck broken by a fox and the vet had to euthanize him or else I would tell you his final size.Unfortunately I live in the city limits. I hope i don't have to re-home.
Do Brahma chickens (hens & roos) really get as big as Google shows pictures of?Or is there a "giant" brahma?
Most of the "giant Brahmas" you see are from overseas where they do breed them to be a bit larger but even ones from the US are pretty huge still!
