My little flock of 10 turned 8 days old. I have 7 Barred Rocks, 1 Silver Laced wyannadotte, 1 Silver Penciled Rock, and 1 Golden Buff. Six of my chick's 5 barred rocks and 1 wyannadotte will fly into my lap and cuddle with me. They sleep in my lap and perch on my arms, fingers, and Chest. My Golden Buff is very shy as is my Silver penciled Rock and two barred Rocks they don't like being held although they come to the front when I call them. Never in my life have I had such friendly babies! I definitely think the six are imprinted on me. But not the other 4. I wonder why that is? Here six chicks fly to my lap when I open the cage door (dog cage brooder) but I wonder why the other 4 are so shy? They are the same breed except for the Golden buff, and the penciled is still a Rock. Why are 6 so extremely trusting and friendly and the others are not? What do you think?
