You have to remember that it is not a easy thing to mix small batches of feed. Most mill are set for cattle &/or hog feed by the ton.They asked me is I was feeding turkey feed to my chickens because I requested 20% protein and then told me I needed layer feed with 17% protein. They weren’t willing to make anything special for me. Which I thought feed mills could do.
Thank you everyone. It’s good to know I can feed starter to my whole flock. I didn’t know that. I’ll be looking into different mills and calling the local extension like suggested. There’s plenty of mills around me. Not just the one I contacted.
