6 of the chicks that I bought were GLW. They are 2 1/2 weeks old now. 5 of them don't have a comb, just a pretty wide flat skin area on the top of their heads with just a hint of the waddles. One of them has a comb...but not a comb that looks like the ones in the pics I have seen of Wyandottes. This one's comb looks just like the combs my BO's & Barred Rocks have. I am a little confused....could it be mixed somehow? Do you think this is a Roo? They came from healthy chicks & more. This one also feathered out much quicker than the rest.
