My weird chicken hates baths -- room temperature, cold, misting, dishes, whatever I've tried she absolutely hates it. She's only stood in her bath once and then climbed out without really...bathing.
Which, of course, means I have to chase her around with a mister every so often, which even still doesn't get her wet enough to count as a real bath. Her skin looks dry when I move the feathers out of the way, so I know she'll need a proper bath soon. She's only bathed once in a cool mist bath after we got her. She loved it then but nothing is up to her standards now.
I've never tried a shower perch to see if she likes that, because the tap water where I live ( Tampa ) recently became toxic to birds and rodents. Will bathing water be safe to her? Is a shower perch worth trying?
