5 toes?

[Golden Phoenix]

I hatched a d'uccle bantam and I just noticed she has 5 toes on one foot! Why are there 5 toes? Her mother and father might be brother and sister, but I don't know because I didn't hatch them.

Wow! I've never heard of a D'uccle with 5 toes. I bred a brother and sister (Jersey Giant) together and the chick came out fine but It was born with side sprigs, a disqualification. But I guess 5 toes on a D'uccle can happen like a rare baby white buffalo calf.
