You can put it or not. If tin foil is not used, the temperature should be controlled well, about 150 degrees. The time depends on the size of the food, usually about half an hour. Before roasting, it's best to make a few cuts on chicken wings or chicken legs with a knife, which will make them easier to cook. If you put tin foil, the baked goods are also good, the color is easier to master and the baking tray is easier to clean. It's best to wrap chicken wings or chicken legs in tin foil, and take them out of the tin foil and bake them in a baking tray for a while when they are half cooked. Mainly the meat wrapped in tin foil will produce some steam and taste delicious. When it is taken out, it will taste more tender and fragrant as long as it is dried.
