What temp do I bake chicken drum sticks on ?

For almost anything if in doubt 350 and keep an eye on it

I do 30 minutes at 425. This is my favorite recipe:

30-40 minutes at 350 is what I good my chicken legs at and they always turn out great.

It can vary depending on the preparation, but 30 minutes at 400, and then 10-15 at 350 should do the trick if you're just simply roasting them. There are loads of recipes out there, you can take your pick! Take a browse, and see what might work best for you : http://www.food52.com/recipe/chicken%20leg
