DROM: I do notice a tinge of cream color in Bruno's current feathers. But, I seriously attribute it to the feed. When the boys were younger, they got DUMOR 24%. And I never noticed any of the creamy coloring or yellowish color. My friend raises White Orps, she has that as an issue for her birds. She has to feed a different feed to the birds she shows. DUMOR has pork as the source of some of the proteins. Now I use Flock Raiser and Layena mixed together. I never noticed till that question. But, I think the feed night have something to do with the Birchens looking Silver then a smutty off cream.
