I recently came across a chicken cooking guide. I really liked the recipe that is on this page.

I think you will like it too.

Steps

• Step 1
  Preheat oven to 425F.
  
• Step 2
  Wash your chicken legs and trim the excess fat.
  
• Step 3
  Rub them with salt, pepper, seasoning and sprinkle with olive oil.
  
• Step 4
• .....

That is only half a recipe! your link doesn't work and you did not say how log to cook, covered or uncovered. 425 is a high temp for chicken, especially for legs.
