I also have 3 chain hooks welded on the bucket. The bucket is a heavy duty model that has a reinforced top support tube, so welding to that provided plenty of muscle for lifting. I use the chain wrapped around the chain hooks on each side to evenly distribute the weight across the loader bucket, unless I am lifting something weighing only 2-300 lbs. Then I may only use the center hook.
Just make sure you have plenty of reinforcement on the bucket edge so that you do not bend it, then make sure you have a competent welder put them on for you!
