I have dark brahma girls and love them to death. They are super friendly however dont like to be touched. When I pick them up, boy do they yell as if I'm killing them but they really dont fight much, just yell. From what I have seen and heard from brahma breeders, brahmas dont do overly well with high heat and high humidity. Chickens release their heat through combs and wattles and since brahmas have very small combs, they arent the best in the heat. Cold, on the other hand, is no problem at all. Very cold tolerant.
