We have a yearling that we rescued about a month ago and are working on getting weight back on. Doc told me to put him on a light, easy feed. I got some weanlean/yearling feed from our local TSC, but after reading a lot of posts on here, would I be better off with a senior type feed to give him more calories??? Have been trying to find beet pulp, but I can't even get it at the feed mill where my hubby works. He is also on grass hay, keeping his feeder full so it's always there when he's hungry. Also been doing a lot of walking to try to re-build mussels. We walk for about 30 mins every morning and the same about 3 night a week. He's gaining steadly and i'm loosing!!
