Chicks at Five Weeks

Asymetrical chick may be a "gynandromorph"

Gynandromorph chick at 5 weeks

Last week I noticed that one of the 5 week old chicks has different colored feet -- one white, one yellow. Its feathers and waddles were also asymetrical, so last night I decided to look into it on BackyardChickens.com.

After posting some information and pictures in their forum, I got feedback that it could be a gynandromorph -- half male / half female. Apparently this can happen if an egg was fertilized by two sperm.  Here are some photos. The left side looks male with a red waddle and thick yellow leg. The right side lacks the waddle and the pale leg is thinner like a hen would have.

I'll post more photos as this one matures when there's more to see!
