I ordered 15(got 16) Golden laced wyandotte chicks from Mt. Healthy Hatchery in December. They are almost 8 weeks old now and we noticed that two of them actually have a single comb instead of a rose comb. They are all supposed to be pullets. Does this mean anything? These were the first chicks we ever ordered from a hatchery. We also go a silver laced wyandotte instead of a golden too. Is that common, that they mix up the breeds? We don't mind though she is a beautiful bird. Anybody with any info would be a great help. Thank you in advance.
