One of our older RSL hens, Drumstick, has begun behaving in ways that I think are very roo-ish. She bawks almost constantly while patrolling the yard, becoming even louder when she hears a crow, raven or hawk (or sees a cat). She has even developed spur bumps! Is this normal? How can I get her to shut up? FWIW she and her sister Crockpot are on their way to the stew pot as soon as the young man who will process them is ready for them. But in the meantime she is one annoying loudmouth!
