Well, this posting makes me feel a bit better! My five chicks are now 3 1/2 weeks old, 2 silver wyandottes, 1 gold wyandottes and 2 rir...but at the same time I'm still nervous! I too must have pullets, and I bought sexed birds!!! But one of the rir's has a larger comb on top, and a longer tail...the other a bit smaller, one wyandotte has the beginning of a comb on top, longer tail and the other two don't have anything!!! When will I figure this out, when they all starting crowing?!!!!
