I have in my care two pekin ducks one came from a shelter another was rescued by my daughter's boy friend. Neither had access to water for bathing in a very long time if ever. As soon as they got into the aviary they both got in the tub and splashed and dove all night this morning they finally got out and had some layer mash and romaine lettuce. It is probably the first time they have also had a companion duck. My concern is their bills appear to be terribly discolored. My guess is poor diet and no bathing facility combined to cause this. Are there things I should be adding to their diets to improve this or will it correct in time with proper husbandry? I was thinking of speeding up the cleanup process by giving them a shampoo but I really don't want to remove the oils from their feathers and think they will clean up naturally over a few days.
