I saw this post, hoping someone who knows about ducks could help. My Rouen duck was attacked last night by a enormous raccoon. His back looks like hamburger, but does seem to have gotten to vital organs just feathers and skin. Nope, no bird vet out here. Not sure what to do. Sweet duck, lets you pick him up for love.
Some very basic instructions there. Basically I pluck the pluck-able feathers 1/2" away from the skin edges. Pluck in the direction they're growing to avoid tearing the skin. If you think the skin might tear, cut with scissors.
For cleaning I use chlorhexidine or betadine.
Can you post some pictures?
