I raised 3 heritage turkey chicks with 19 chicken chicks of various breeds. All from a clean breeder in town. My observations: The turkeys are VERY docile and get picked on. Even though I only had a 3:19 ratio, I didn't have an issue. My marans were the biggest bullies, one cockerel kept trying to breed the two female poults at 2 weeks old! Everyone's almost 6 months old now, and no problems. Even though the turkeys are nearly double the size of my biggest orpingtons, they still get picked on a bit.
