My two Light Brahmas have always been the aggressive ones in my little flock but since Dolly molted she has been just downright mean - has even pecked at me a couple of times and won't let my little bantam EE get up on the roost at night if I don't intervene. She was very withdrawn while actually molting but once she started to feather out again she got more and more aggressive. She looks beautiful but acts so ugly, is this normal? Her sister, Blondie, doesn't seem to be any different personality wise. What's a mother to do?
