Per UK Standard any color legs and feet are accepted.
The American Bantam Assoc. Proposed Serama standards say nothing about leg and feet color. The only disqualifications regarding legs is creeper legs and a defect is short legs.
On Serama.com Six Feathers Seramas there is a set of standards that again say nothing about leg color.
Oh and Calico and the un-named rooster are Chets sons and Chet indeed has yellow legs. I'm not home at the moment to double check leg color on Calico and Chester but yes the pics show white.. If I remember correctly Chester has pale yellow tho.. I can't remember off hand what color Calicos is for sure. Broody the hen also has pale yellow.
kelliepulido I'm not sure if you mean a,b,c size (which if you do I will find out soon I haven't bought a scale to weigh them yet), Cage size which is 2' wide x 2' tall x 3' deep, or how many are in each breeding group which I have 2 trios and 1 pair.. Hope one of those answers works.. Lol
