I put Coco in the shower every other day. He does't seem frightened as I let him get on his shower perch after turning on the water and he hops right on. How long should he be in the shower? I usually give him a good 10-15 minutes. He doesn't spread his wings or anything, he sits there with his eyes closed. (Picture). Also, a lot of people seem to shower with their bird but don't they need to shower in lukewarm/cold water?
