Yellow feet ... Jersey Giant, but at 12 weeks she should be significantly larger than her age-mates. If those are all the same age, you either have a slow maturing JG or a hatchery baby - or both. Either way, JG's are awesome birds. They grow slowly - not reaching their full size until about 18 mos, and generally have a very pleasant disposition. I have one JG hen in a bantam flock (she TOWERS over her buddies) but she lays huge brown eggs and is about the sweetest bird I've ever had!
