I have 6 steers that average 4-450. I have been feeding a 14% commodity feed at 7 lbs/head a day. Free choice mineral and are on a 1.5 acre lot with grass. Had the calves for 2 months and I don't know that there gaining (no scale to know for sure). I feel that I'm doing somthing wrong in my feed rations. Any advice would be appreciated greatly. This is my first jab at backgrounding
