Speaking of Heavensent Ranch. Quality breeder, real nice people there. A good place to get real quality foundation stock for a flock if you decide to start over again. I don't work for them or anything, just known them for years. Will be there for you after the sale. If you need to start over again, get some started birds, if you can. Even some of last year's breeders is a great idea. That way you redeem the time lost with faulty birds and get to stay on track for next year's breeding season. Now is the perfect time to inquire as breeders trim their flocks for over-wintering. I did this in Sussex and don't regret it.http://www.heavensentranch.com/orpingtons.htm
The link above is some information about the "Standard of Perfection" in Orpingtons by the American Poultry Associations. If you read the first paragraph, it will mention that having yellow legs is a disqualification, which I believe could be the result of hatchery-stock chicks. Hope I helped some.
