Sultans, due to their unique look, are most used as show birds. They can still be used as decent layers in a pinch, but their strength is as an ornamental show bird.
Sultans has a placid nature, making them a simple chicken to keep, despite the added maintenance needed due to their extra feathering. Still, they're calm, even when showing, making for an easy show bird.
While Sultans are a small chicken, their obvious feature is their uniquely shaped head, completely covered in feathers to create the appearance of a globular feather poof atop their head. They don't have wattles, instead having a sort of three-part feather beard. Their tails are well-spread and carried medium high. Even stranger, they have blue feet that are completely covered by feathers, though what makes this strange is that they have five toes rather than the standard four.
Because of their facial feathering, Sultans will need a special drinker, such as a water tower. Because of the feathers on their feet, they do best in clean, roofed-in runs, though it's not advised to place perches too high for roosting.
