Yes, the poofy cheeks are one difference in Cochins and d'Uccles.Thank you CochinBrahmaLover, I see it now.
JulieChick, I was actually thinking the same thing because the only pictures of chicks I can find that look like #4 are porcelain D'uccle. I am still new to this and haven't been able to find what the difference is between the Cochins and D'uccles...is it the poofy cheeks? Because #3 my suspected Millie Fluer does have poofy cheeks, they didn't come through in the picture though.
