Turn up your volume because she's kind of quiet (Chy, not me).
I've been wanting to get her on video braying for a while and finally she did it on cue. She does it a lot now that she's discovered how to get attention. Yesterday she was full of herself and probably did it more than a dozen times. Sometimes it sounds more like heehaw than others. At times, when she's really loud, James says she sounds like a fog horn. I'll try to get a louder one another day. I need to carry my camera around more.
