Hi, I have two silkies that I'm trying to determine whether they are roos or pullets. They are 9+ weeks old and there hasn't been any hints of crowing yet (not sure when silkies start). Also what color would you say they are? Chick 1: Larger of the two, I think hatched mid to late December. Lighter in color, white with slight hints of tan'ish color. (ignore my cochin photo bomb ) Chick 2: Smaller one, hatched beginning of January. White background, but much more of the tan'ish color highlights. Thanks in advance!!!
