So, I have had my minis for about 6 weeks. I am feeding a grass hay and using Nutrena Topline ration balancer that I could buy at Tractor Supply. Now the TSC has stopped carrying it! I got the last 2 bags so I could do more research to find something equivalent and have enough to slowly switch to a new brand. I liked the idea of being able to run to the store when I needed more, but am willing to have balancer delivered if necessary. How do I find an equivalent? Do you have recommendations? Thanks!
