Feather Fixer is essentially a gimmick, IMHO...
It basically has 2% more protein than layer at 18% verses 16%. I would go all the way and get a flock raiser (20%) or un medicated starter (22%) for at least the first bag or until the issue is corrected. As long as you provide OS on the side, it will work for everybody in your flock.![]()
Maybe watch a video of peepers being applied. I've never done it but it always good to see examples, I would think...![]()
I wouldn't call it a 'gimmick'. It isn't just about the amount of protein. Feather Fixer has chelated trace minerals to support feather regrowth and sulphur which is, as far as I know, one of the few effective treatments against knemidokoptes laevis var. gallinae, commonly called the depluming mite. It isn't a gimmick; it's a different formula.
