I don’t know if this is the right place. 4 days ago I started my 2 year old on this balancer. It says 1/1.5 per 1000 lbs. I weight taped him, which I know is not the most accurate in the world, but it came in at 1001lbs and it was held pretty tight. He is up to 1 lb. Do I keep uping to 1.5 lbs or stay at 1 lb? He is on free choice grass mix hay. Thanks.
