Easy way to shape the thigh, bring a large pot of water to the boil, large enough and deep enough to allow the lower part of the thigh to be submerged. You only need to hold it in the boiling water for 15-20 seconds, pushing the thigh piece together to give the front a more rounded shape, then as soon as you remove it from the boiling water, place under cool water, or a pot of cool water. It will retain the shape. Best to try it a little at a time, to get the right rounded shape.
