I try to spray Timber daily because he likes it. There is a difference between a spray and a full bath. Timber likes being sprayed, but does not open his feathers when I spray him. In other words, it isn't getting to his skin. When he is ready for a real bath, he will splash around in his water bowl. I get the pan I use for him to bathe (think 8x8 or 9x14 glass baking dish) and put some nursery water (untreated, purified, no additives) in the pan. Then he will go at it on his own, dipping his head, feathers, tail etc. throwing it over his shoulders, and gets really soaked to the skin. Others with more experience will probably give additional advice
