I have seven bantams, five are Silkies, one D'Uccle, and one Cochin. Right now they are about 12 weeks old. The feathers of the D'Uccle and Cochin look great. The Silkies are mostly fluffed out, but still some scraggliness. They haven't seemed to be growing much lately. I'm just wondering if they are still feathering in, and at what age are they full grown, as in full size?
