I have a plastic bin that's meant for washing dishes. I use it for washing my chickens. I do the bathing outside. I fill gallon jugs with warm water. I put a gallon of water in the pan, then put the chicken in slowly. Pouring dilute dishwashing liquid on once the chicken is wet, i let them sit for about 10 minutes after i lather it up on the bird. I lift the chicken up out of the water. Then pour clear water on the chicken until all the soap is out. Wrapping the chicken in a towel , i dry it off. Then i put the chicken in a cage and point a small personal heater at it until it is completely dry. Palmolive is my liquid of choice as it will kill bugs, but i may use blue dawn if the bird has foreign substances in its feathers.
