I have been using powdered catfish feed for over a year on my chickens at a rate of only 1-2% it is strong protine at 28-32% if you use to much your chickens heads will turn red from being to hot for them. I use a 32oz. cup and I use 4 scoops of chicken grower finisher feed and a 1/4 scoop of catfish feed. However if I use two full cups of catfish feed in a 5 gal bucket of chicken feed the hens can go thru the molt and still lay eggs the whole time. But that is how I mix mine.
Glad to have your measurement. I had no idea how much to add. Thanks.
