Mine does. Last summer before I got all the extra roosters penned up and they'd chase my poor pullets around, my dog would intercept them. He wouldn't touch them, just get between them and the girls. He also breaks up any squabbles between the chickens. He just gets in the middle of the fray. His favorite sport is chicken bowling. He waits until they're in a bunch, doing their chicken thing - pecking and scratching - then he'll run full blast through the middle of them, scattering them everywhere. He stops and looks around like, "Huh, who did that?"I am thinking some dogs make very good roosters :}
