I just purchased 4 new chicks at 2 different ages. I got 2 sex linked chick at about 2 weeks and 2 brahmas at 1 month. They're all hens except for one brahma which is actually a brahma silkie mix. I have a 3 month old amauracana rooster currently that I've had since he was about 3 weeks old. What is the best way to introduce everyone to make a happy flock. ( The 4 new ones are all practically a flock already) All tips would be helpful.
