My cows love feed. I give them about 3 lbs a day. They have all the hay they want. Around 10:00, they will be content laying around. Ok, here is the problem. When I go and put out minerals loose), they want to eat it like food. Yesterday in 30 minutes, they ate 100 lbs. I know some will say, it is because they need it, and I agree, but I could go through 1000 lbs of mineral before they stop. I fed th, while they were full,but it did not help. They just eat the minerals like feed. Any suggestions
