Best shampoo for poultry

I’m just wondering I’m looking into showing some of chickens and ducks and was wondering what the best or safest shampoo/ soap was to bathe them in to make them clean and shiny and not smelling like a farm animal lol...

Dust

shampoo would wash all the oil off and make them look terrible, http://counties.agrilife.org/harrison/files/2011/06/ps03700.pdf there's instructions there in how to wash and which birds might need washing.

Candice, here is an article on how to show chicken that you might find helpful.

What I found that you might be interested in is the part about training the birds.

The article suggests using a gentle shampoo with a rinse of apple cider vinegar to get the shampoo residue out.

On another website, there was a suggestion to use baby shampoo.

I'm no expert but my sister inlaw has some of the most outstanding looking chickens ive ever seen and she just keeps the pen clean lets them run around in grassy places and makes sure they are fed well with organic natural feeds and they never need to be bathed.
