I know getting water up the nose in a human isn't that great and so a chicken wouldn't be either but...what if it does happen and the water gets in their nostrils? Do they choke, get sick, what happens? How do you wash their crests and not get the water in their nostrils?most people put them in the sink filled with warm soapy water, I like to use the sink hose and put the shampoo on straight. You can use just dawn or you can use a dog shampoo, whitening works best for whites. But nothing with tea tree oils or that is tearless those are bad for them. I just gave my polish a bath in fact. After rinsing the soap off rinse him in water with a little apple cider vinegar, it will cut through any remaining soap and moisturize the feathers. I prefer to blowdry my chickens(on semi-warm, not too hot) after the bath but many people will just put them in a pen with shavings and a heat lamp to dry off. Just make sure they stay warm while they are wet. and don't get water up their nose or soap in their eyes.
