Pale yolks?

[chickboss]

I was just told by a lady who also sells eggs (she bought some from me because she sells so many that she doesn't have any left for herself) that my yolks were quite a bit paler than hers. Mine are on a locally manufactored organic feed, hers are on the typical Purina fair. Not sure if I am looking at a some kind of problem that should need supplements or if it is just fine. I have a couple of hens that produce a darker yolk, one that produces a lighter yolk and most are right down the middle. I just kind of assumed that breed played a part in the variation. Any ideas?

Does she offer hers grass? Grass makes yolks darker.

Yeah, but just like mine it is all dried out this time of year and hers are still dark aparently.
