I grew up with chickens. We had Rhode Island Reds and Barred Rocks. I remember the BR's being more approachable. Last March, after having mulled it over for several years, I decided to get myself some chickens again, and through research, found that the most commonly recommended breed for having as a pet was SILKIE. Our Silkie loves to sit on laps and watch tv, and enjoys being an indoor house pet.
My hand raised Barred Rock chick, at 8 weeks is also very snuggly, loves to sit on our shoulders as we walk around the house, and even enjoys riding on my dog's back. It's hard to say though... could ANY breed of chicken when hand raised as a house pet be this tame?
