the variation in the chick's coloration seems to be at least partly due to the rooster
from what we have seen so far, he is basically a silver duckwing, but carrying Columbian genes, and possibly gold also
the hens all APPEAR to be gold duckwings, but we are guessing that several of them may also be carrying Columbian genes
two of them (Deirdre and Phoebe) have partly or mostly black heads, and are clean faced (the other four are muffed and bearded)
Ginger is perceptibly more mahogany colored than the other five
I'll have to get into DH's computer to get pictures of them as several-week-old chicks (his camera is lost; no idea where, we know he had it at the Sounders' game, hasn't been seen since)
my memory says there were four mostly-yellow/gold chipmunk chicks, one brown chipmunk, one rusty red chipmunk, and one quite-dark-brown NON-chipmunk, who turned into the rooster (black and silver feathers replaced the mink-brown as he feathered out)
