So I might have 1 silkie pullet one day soon. Right now I have 2 cherry eggers pullets and by the time I get the silkie chicken my cherry Eggers will be full grown while silkie will be a pullet. So this would be just 1 pullet. How do I integrate her with my existing flock of 4 full grown cherry eggers. What is the best way to integrate one chicken to an existing flock? Ty!
