So we've had chickens a few years now and decided we want to also have ducks. We just purchased some Rouen ducklings yesterday. Now my question is, will our cat attack them once their adults? I know to keep them out of reach now while they're babies, but what about when they're full grown? Our cat is about 15lbs and is a little larger than your average cat. We plan to let them free range next summer. Any help would be appreciated thanks!
