one final thought...
...if the feathers are on the outside of the leg and down the outside toe, she could be a poorly marked Splash Marans. Her leg color looks pale/whitish...maybe grey/white? I suspicion you have a Black Copper Marans in the bunch. Marans have light grey/white legs with feathers on the outside of the leg in the French line. (American line is featherless on the legs). There are White Marans, but those are very rare, so I really doubt she is that.
Her body type is more like a Marans or heavy Rock than a Cochin. She might also be a White Orpington mix as her body looks Orpington like as well...but Marans or Cochin would have to be in the background for the leg feathers....possibly Brahma, but she doesn't remind me of that.
Does she have a single comb? (I think so in the photos...hard to see).
