It is so hard to get all the SOP into one Dom but I love the comb and leader on your girl. Do you ever catch her in a tall alert stance that gives her back a bit of U-shape? I'd be happy with the the look of this hen as I have seen overly fluffy cushions on Doms that make them look more like BRs. I'm wondering if a colder climate makes the Dom hens feather out more cushion at the tail base? or if it's all just genetics period?
We found our Dom quite a pesty girl - imprinted on us immediately when we picked her up at one week old. She screamed if we left the room and we had to keep talking to her so she could find us to follow us. Some chick breeds cower in a corner, or come running for treats, get bored and run off again - but a Dom will linger to explore your fingers, hair, eyeglasses, and ultimately curl on your arm or in your palm to go to sleep. Amazing birds.
Most chickens don't like being held, especially if our hand completely surrounds and holds their body. We found with our Dom chick - to allow her to jump on us where she felt most secure and let her explore without reaching out with our hand to pick her up. She had a ball exploring our clothes, eyeglasses, hair, hopped on our arm and shoulder, and if we had a tasty treat all the better! They are personality plus birds and imprint young on their humans. Spend the time with the youngsters - they grow so-o-o fast before you know it!
