On the rare occasion that I use whitening shampoo, I use Synergy Labs.Here’s a question about exhibiting...I figured it wasn’t worth creating a whole other thread, but I might later if need be.
I’ve seen people use purple dog shampoo or toning shampoo for people to brighten or whiten light colored or white chickens. Does anyone do this and have a recommended brand? Thinking of trying it if we ever have a show again.
