In a few weeks, I'm planning on getting 3 chicks; 2 Australorps and 1 silkie. But then my pop said that you need to get two silkies. Do I? Because the chicks will all be the same age and will be welcomed to the other chickens at the same time. So yeah... Do I need to get 2 silkies if I'm already getting 2 Australorps?
