I have this hen...

[lilwanderer]

So this hen, i rescued her today and she looks to be a silver duckwing of some sort but has five toes, some of her siblings only have five toes on one foot, hers are on both. I know sultans, silkies, and faverolle have five toes but she doesn't look to have that in her i dont see any hairdos, muffs, fluffy feet or silkie fur anywhere on her.

I think Dorkings also have 5 toes and do come in silver duckwing.
Maybe she's a dorking cross

Could be a Dorking cross, but definitely not purebred. Wrong body shape and size, wrong leg color.
