I haven't gotten chicks from Murray McMurray or Privetts, but I have BC Marans and an EE. My experience (which is limited) is that my EE is the spookiest of my birds. She'll hang out on the deck with everyone but does NOT want me touching her. My Marans was the exact opposite--almost always wanted to be on my lap or the other chair while I was out there reading in the evening. They both laid like champs--almost daily with a short break in Dec/Jan. Love 'em!
Oh, also, my gold-laced wyandotte lays smallish pink eggs. Not right now b/c she's in a hard molt, but I'll take pix once she starts back up.
