Can you help with breed/gender for these 4? They are all a little over 3 weeks old. 1. I think this one is part silkie. 5 toes and black skin, but is feathering in differently than my other silkies. 2. This one is a Barred Rock, wondering for extra opinions on gender. Sorry about pic quality... she(?) wasn't being cooperative. pic 1 (front) pic 2 (middle) 3. Is this one a black sex link? I think she said it was a RIR x barred rock. Would that mean it's a female? 4. And last, but not least.... Thanks!
