Our cat Larz watched over the chicks from the day they came home from the feed store in April.. Even when we free range the chickens he is there to keep them together. Recently the smallest hen Odessa (a rode island red) has taken to chasing Larz. Larz still watches over the chickens but from a distance. And when they separate he follows but does not engage. Is there any way to reverse this behavior? I'm sure that Larz will still watch from a distance but I'd prefer it if Odessa did not come looking for trouble.
