I have a very small flock and added two Araucana chicks last Spring. I kept them together as chicks. When they were ready to go out to the coop they fit into the flock perfectly, have adorable personalities and are inseparable. I'm convinced this is the best way to add to my little flock- in two's. This Spring I would like to add two more chicks. I am considering these breeds- Plymouth Rock, Orpington and Wyandotte. If my goal is for them to be "buddies" is there any reason I shouldn't get two different breeds to grow up together? Thanks for any input.
