I'm looking for opinions here.. I want to add a dark brown layer to my flock. I currently have two EEs, an AuLorp (who is in behavioral rehab ha ha) and a BR. They are in a large pen most of the time but also get to free range. I want to add a bird that is curious, friendly and not flighty. Also, not inclined to go broody as I have no roosters. What would you pick if you were choosing between the Welsumer, Barnevelder and Marans breeds?
