the first two pics is the one with the larger pouf on it's head. coloring is more muted brown with some gold/black mottled feathers under the fluff. gold around the neck. the last 2 pics is the smaller chick mostly black, grey and white. I am new to chickens and am baffled by the types of silkies. The girl I got them from said she thought they were partridge. What do you think? (sorry for the bad pic quality) also, any idea how to sex these two? they run around like crazy and chest bump. I thought rooster till I read it's ust a chick behavior. they are around 7-8 weeks old.
