He's driving the hens insane and we can't figure out what he is doing. He keeps going into a corner on my porch on some newspapers and making himself as small as possible and and scratching a bit and making a constant "RRRRAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHH, RRRRRAAAAAAAAAAHHHHHHH" sound. The hens just stare at him like he's nuts, and finally walk up to him and peck him like "dude what is going on with you?" He's been doing it the last few days and today he is just driving me up a wall. Any behavior experts out there?
