A while back on the old Heritage Large Fowl original thread we discussed this. One poster sent in a pic of her bird she had bathed in a dog shampoo esp. made for white dogs. Wow! The before and after pics were amazing. The bird got sooo white. I looked around and (being formerly from the dog breeder world) checked out Chris Christensen's website. They do have a real nice shampoo called White On White which makes the whites clean and sparkle. Might try them.

excerpt from that webpage:
"Dear Lisa & Chris; I had a funny thing happen recently and wanted to share with you. I have 10 purebred chickens. I keep them for pleasure and for the yummy eggs they lay. I recently attended a "chicken swap." The swap advertised that there would be a chicken grooming seminar. Of course, I HAD to attend a chicken grooming class!!! The class a surprise. It was given by a young lady, 12 or 13 years old. She was at that awkward age, and had a fairly significant speech impediment. Yet, this young lady had more confidence than any 12 adults put together. I was wowed. This young lady shows her chickens at fairs and shows around the state. She described in detail how she bathes the chickens, trims their beaks and nails, rubs sweet oil into their combs and wattles. I asked what the best shampoo for chickens was. Her answer tickled me...it was swift and without hesitation. "White on White" is the BEST shampoo for chickens." So, you obviously have an untapped potential market here! You need to be pushing the White on White to the chicken showing world! Hope this finds you both well and happy. Love you both! Daryl"
P.S. Chris Christensen also makes special shampoos for red, blue, and black colored dogs,
