Just be aware of the symptoms of cocci, and treat if they seem sick. You can use a preventative dose (1/3 of the treatment dose) every 3 weeks or use medicated feed with amprollium with your meat birds. Many do that with meat birds. I like to expose my chicks early to the soil by placing a lump of sod in the brooder for them to play with, and so far my egg layers have never had a problem with cocci. Chicks raised by a broody hen on the ground from day one very seldom get cocci. Keeping your meat birds on clean dry litter, and letting them outside on fresh grass may also help in prevention.
