Well imagine that. I bet youre right but i can only go from what ive seen. My buff Orpington is a little stinker and Pearl my white leghorn is a sweetie.
I raised mine from day one and tried to handle them all from time to time to get them familiar with us. They are now 6 weeks. Its a mixed flock. My RSL and White Leghorn are by far the friendliest. The leghorn just flew up on my shoulder today! But the other ten are not nearly as comfortable...
