My local farm supply has 4 different brands of layer pellets but nothing else but medicated chick crumbles. My chicks are 10 weeks old and I really don't want to feed them the high protein starter and feeding them the high calcium layer pellets is a no-no. The feed store has turkey finisher. It is 16% protein with no extra calcium. What could be the difference between turkey finisher and chicken grower? Do they add something into turkey feed that chickens couldn't eat?
