Well, I have lovely Blue Laced Red Wyandottes, that are six weeks old. What i'd like to know is this: can they have their first dustbath with food grade Diotomatious Earth yet? I'm not sure whether to mix with sand or straight up! They aren't in their coop quite yet, but do go outdoors each day, and I'd probably let them bathe outside, then bring them in. What do you think?
