There is much debate over how Quakers prefer to bathe. Like eating, bathing is also a social activity for birds. Give it 'til your birds first bath, and it will also be one of your favorite times of day. A Quaker playing 'Splish-Splash' in an inch of water is all it takes most folks to melt like butter. There are, of course, some pointers available, if you're interested in making the most out of this activity.
Bathing is a truly great behavioral enhancer.
Wetting the featheres encourages the Quaker to preen the feathers, which is a time consuming, somewhat tiring, endeavor. The more time your LGC spends completing constructive, self rewarding behaviors, like bathing, the less time he has for screaming, plucking, and biting. Bird feathers are covered in oils secreted from the birds skin. When feathers become too dusty from dander and dirt, the oil no longer spreads throughout the feathers, and they are neither protected, nor conditioned. Dirty feathers harbor bacteria, become matted, itchy, and eventually cause illness and misery.
