I used a turkey starter (24% protein) for 5 or 6 weeks. I then switched them to 20% protein feed for another 5 weeks. I used only non-medicated feed. I never had any issues with them. They were all very healthy. Mine had plenty of exercise. Their feed was a good distance from their water and they had to go outside the coop to get to it. Mine also free ranged. That probably made a difference, too.
