Some of her early pictures look like porcelain d'Uccle by the color. Some older ones look more white Cochin or white d'Uccle. Hard to say. Keep sending updates though. Someone will figure it out eventually!
Feathered feet certainly narrows it down.
Cochin, Brahma, French Maran, faverolles, sultan, d'Uccle, and a few more. To further narrow the possibilities, count the toes. Most have four, some have five.
Is it bantam or standard size?
Does it have a straight comb or Rose?
These will help narrow...
