I don't know how to best clean up pooh but you just made me smile. Glad I'm not the only one that likes to drink a few beers and have some fellowship with my chickens!
I do know for down jackets and down sleeping bags it is possible to put them in the washing machine but you MUST put some clean tennis balls or 'dryer balls' into the dryer for drying. They bounce around and fluff the down while its drying. Otherwise the down clumps in a corner, doesn't dry, and sort of ruins the blanket/jacket/etc until you can successfully fluff out the down on your own (which never happens). But the dryer balls work great- just did a down jacket yesterday.
Good luck!
