Wish I had a tag here to tell you the exact percentage....my local feed mill uses fish meal in making their chicken feed. It is combined with corn, roasted soy, and a variety of other grains as well as nutritional suppliments. No nutritional problems here. Lots of happy egg producing chickens.
All of the grains they use are grown locally and they mix in weekly batches and dated so I know that the feed I buy has only been ground for a week at most.
I'd check your labels because if you are buying layer or grower you probably allready have animal protien in there because it is widely concidered a basic nutritional requirement. My girls get extra animal protein to replace the bug loss over the winter by means of dairy and scrap meat and fish from the house and go wild over it.
Yesterday I gave them potroast scraps and they went nuts...today lettuce scraps and they aren't interested.
