I did a bit of research and I believe you would just call it a local chicken breed or an Arabi chicken! I found quite a few pics of other native chickens from Kuwait with buttercup combs too! I understand them to just be a sort of landrace breed, so their appearance can vary! Please continue to update! It will grow up to be cool looking bird
