Don't you wish they were easy like chickens to sex? ha. I do believe I have a pair I'm not sure one makes that buck-wheat sound all the time and I do mean ALL THE TIME(especially when someone walks to the pen) The other one however is mostly quiet only making little whistling noises and chirps. I've only heard it get loud once and that's when they first seen our big dog. The sound was horrible. lol When they were younger- the one with alot of white on it is the buckwheater the other ones feathers go almost all the way up its neck and fan out a bit into a collar like thing.
