I’d say both are Muscovy they are a great breed of duck very hardy they do fly though so keep that in mind if you live where flying maybe dangerous to them neighbors with dogs, traffic or just flying off where they may not make it back. I clip my Muscovy wings since we live very wooded and have lots of predators. I don’t want mine flying at all they live in a fenced half acre with housing for nighttime. They love bugs so they will keep the bug population down and eat mosquitos and larve but they also need some feed for a well balanced diet. They really are special breed will wag their tails like a dog and can learn their names. They do need secure house for night time if Hawaii has predators .
