Thank you SO much for all your help! I was SO worried about buying unsexed chicks, but I guess I won the "pullet" lottery so to speak. I know the silkies are hard to sex...I'll be patient.
And by them not having much of a personality (the silkies), they were that way before they got their huge crests. The black one in particular HATES being touched, let alone picked up...was that way from day one. I bought them from a breeder that only breeds to show/sell his high dollar "show" chickens as he's a poultry judge. Not sure if that has anything to do with personalities. I had just always heard how "sweet" and "gentle" silkies were, and so far, from these two I'm not quite on the silkie "bandwagon" so to speak.
The calico cochin is the sweetest, funniest, and most entertaining of the bunch...her name is Clementine. She puts my other cochin (hen) to shame in the personality department.
