I have always had a flock where they were all different breeds. I do have two EE but they look nothing alike. I now have 3 Sapphire Gems who are 13 weeks old. They broke in to the coop before I was ready to mix them at less than 6 weeks old but had no problems at all. They are very clanish and have like made their own little flock within the flock. One sweet little EE wants to hang with them so much but they will not let her, If she comes near them they chase her off or all three walk off and ignore her. I do like having an assortment of breeds.That is my goal. I am getting a mixed flock going. I have 8 so far, no 2 are the same. First 4 are about 12 wks old and the new babies (4) are 2 wks old. I am so excited to see them when they are all beautiful and full feathered! Yours are all gorgeous!
