I purchase my feed. It's called Nutrena Naturewise Meatbird Non-Medicated Poultry feed.
Specs:
A complete, nutritious vegetarian meatbird diet—no need for supplementation22% protein and fortified with vitamins and minerals to support strong, healthy birds. Contains a proprietary blend of nutrients to naturally support the immune system and overall health of the bird. NO added antibiotics or hormones. Added marigold extract to improve skin coloration. Added prebiotics, probiotics and yeast culture that support digestion. Formulated for multiple species of meatbirds, including broilers, turkeys, ducks, geese and pheasants. Crumble form encourages consumption.
Feed free choice all day (say 6a to 6p). Remove feeder for the rest of the night.
Resume same next day. Always have water available.
Some folks have more strict feeding schedules but this works well for us.
