I am feeding fermented whole grains to my birds now. The mix I have been using is adequate protein wise for my adult flock, but too low for growing chicks. So I got some fishmeal to add to the FF for the chicks, but I am not sure how much to add, per five gallon bucket. Can anyone give me hints on this? I am thinking there is at least one other person on here that does this, since I got the idea here. Thanks!
