DD is going to be entering her bantam Ameraucanas in her first show next week. In the past we've always bathed her showmanship birds (who also happened to be white) on Thursday for a show on Saturday. I know she needs to wash her two wheatens, but she's also entering two blacks. If she bathes the blacks, will it mess up the green sheen on their feathers by stripping oils or something? I don't want her to make a dumb newbie mistake, she's so excited about the show, but I haven't a clue about this one.
