*Darth Bantam and I live together, so we share the chickies*
Some of the feathers are similar to SS, but that doesn't explain the ridiculously long legs and tan facial feathers, and the concentration of white on the breast. She/he has always been extremely docile and subdued compared to the others. She is from TSC bantam assortment, and we were told they come from Privett Hatchery at this location.
Right now, my best guess is a weird looking Spangled OEG.
I don't see why not. Hatcheries do have modern game bantams, and the assortments are whatever chicks are leftover from specific breed orders. I can't think of any other breed with those crazy long legs.
