Why do you slice whole ducks in half when roasting but not for other poultry?

Question

Last time I made a roast, I used a recipe from BBC good food. Since I have had luck with those recipes, I decided to go for their roast duck recipe.

That recipe involves cutting the whole duck in half and roasting the halves with the skin pointing up. I have never roasted a bird like that before, and I am wondering why someone would do it. Does it have to do with the flavor of the meat? Proportion of fat? I don't think I'd ever do that to a chicken because I'd be afraid the meat would go dry. But obviously the flavor of duck is different, and maybe if I know why people do that, I can use it intelligently in my cooking.

Answer

The main reason why you want to cut the duck in half and roast them with the skin side pointing upwards is so the skin of the duck is nice and crispy. Unlike most roasted poultry where you don't eat the skin, the duck's skin is considered a huge delicacy if it is crispy.
