My Pops was a stickler for getting heritage purebreeds in livestock/poultry so I never had Cinnamon Queens, EEs, or any hybrid/sexlinks. After the bad experience my egg-seller friend had with her hybrids/sexlinks I don't plan to try them. From what I understand the hybrids are pretty mellow so probably understandable why your EEs were more active around them. EEs and Ameraucanas are high-strung fowl - friendly, kooky, cuddly, talkative, but definitely hyper-alert, klutzy, jittery types. Love them because as an active breed they are not flighty and stay put in the yard. They are so hardy, predator savvy, seem to enjoy human company, coo or talk with you, sleep in your arms, let you pet them, terrific layers, and non-broody. In fact 3 of our 4 hens went broody this year (including the Buff Leghorn!) except not the Ameraucana. She was the only one giving us eggs in winter and eggs while everyone else went broody. She's our Star in the flock and pet friendly too. A lot of times the typical nature of a breed can alter depending on the surrounding breeds and ages in the flock mix. Example: we no longer keep fowl over 5-lb and only gentle natured friendly breeds with our 2.5-lb Silkies so they don't get bullied. We had to rehome a vicious bully 7-lb Marans and an aggressive White Leghorn who both became excessively domineering over the rest of the gentle flock. Normally the Marans and White Leghorn are quiet or mind-their-own-business types but in our particular flock mix it was too tempting for them to bully the smaller gentler birds.
